But this is only in compliance with the demand long familiar to us, that the psychic apparatus must be constructed like a reflex apparatus. The reflex act remains the model for every psychic activity.

We have now reason to admit a first differentiation at the sensible end. The perceptions that come to us leave a trace in our psychic apparatus which we may call a “Memory trace.” The function which relates to this memory trace we call the memory. If we hold seriously to our resolution to connect the psychic processes into systems, the memory trace can then consist only of lasting changes in the elements of the systems. But, as has already been shown in other places, obvious difficulties arise if one and the same system faithfully preserves changes in its elements and still remains fresh and capable of admitting new motives for change. Following the principle which directs our undertaking, we shall distribute these two activities among two different systems. We assume that a first system of the apparatus takes up the stimuli of perception, but retains nothing from them—that is, it has no memory; and that behind this there lies a second system which transforms the momentary excitement of the first into lasting traces. This would then be a diagram of our psychic apparatus:

It is known that from the perceptions that act on the P-system we retain something else as lasting as the content itself. Our perceptions prove to be connected with one another in memory, and this is especially the case when they have once fallen together in simultaneity. We call this the fact of association. It is now clear that if the P-system is entirely lacking in memory, it certainly cannot preserve traces for the associations; the individual P-elements would be intolerably hindered in their function if a remnant of former connection should make its influence felt against a new perception. Hence we must, on the contrary, assume that the memory system is the basis of the association. The fact of the association, then, consists in this—that, in consequence of the diminutions in resistance and a smoothing of the ways from one of the Mem-elements, the excitement transmits itself to a second rather than to a third Mem-system.

On further investigation we find it necessary to assume not one but many such Mem-systems, in which the same excitement propagated by the P-elements experiences a diversified fixation. The first of these Mem-systems will contain in any case the fixation of the association through simultaneity, while in those lying further away the same exciting material will be arranged according to other forms of concurrence; so that relationships of similarity, &c., might perhaps be represented through these later systems. It would naturally be idle to attempt to report in words the psychic significance of such a system. Its characteristic would lie in the intimacy of its relations to elements of raw memory material—that is, if we wish to point to a profounder theory in the gradations of the resistances to conduction toward these elements.

We may insert here an observation of a general nature which points perhaps to something of importance. The P-system, which possesses no capability of preserving changes and hence no memory, furnishes for our consciousness the entire manifoldness of the sensible qualities. Our memories, on the other hand, are unconscious in themselves; those that are most deeply impressed form no exception. They can be made conscious, but there can be no doubt that they develop all their influences in the unconscious state. What we term our character is based, to be sure, on the memory traces of our impressions, and indeed on these impressions that have affected us most strongly, those of our early youth—those that almost never become conscious. But when memories become conscious again they show no sensible quality or a very slight one in comparison to the perceptions. If, now, it can be confirmed that memory and quality exclude each other, as far as consciousness in the Ψ-systems is concerned, a most promising insight reveals itself to us in the determinations of the neuron excitement.

What we have so far assumed concerning the composition of the psychic apparatus at the sensible end follows regardless of the dream and the psychological explanations derived from it. The dream, however, serves as a source of proof for the knowledge of another part of the apparatus. We have seen that it became impossible to explain the dream formation unless we ventured to assume two psychic instances, one of which subjected the activity of the other to a critique as a consequence of which the exclusion from consciousness resulted.

We have seen that the criticising instance entertains closer relations with consciousness than the criticised. The former stands between the latter and consciousness like a screen. We have, moreover, found essential reasons for identifying the criticising instance with that which directs our waking life and determines our voluntary conscious actions. If we now replace these instances in the development of our theory by systems, the criticising system is then to be ascribed to the motor end because of the fact just mentioned. We now enter both systems in our scheme, and express by the names given them their relation to consciousness.

The last of the systems at the motor end we call the foreconscious in order to denote that exciting processes in this system can reach consciousness without any further detention provided certain other conditions be fulfilled, e.g., the attainment of a certain intensity, a certain distribution of that function which must be called attention, and the like. This is at the same time the system which possesses the keys to voluntary motility. The system behind it we call the unconscious because it has no access to consciousness except through the foreconscious, in the passage through which its excitement must submit to certain changes.

In which of these systems, now, do we localise the impulse to the dream formation? For the Sake of simplicity, let us say in the system Unc. To be sure we shall find in later discussions that this is not quite correct, that the dream formation is forced to connect with dream thoughts which belong to the system of the foreconscious. But we shall learn later, when we come to deal with the dream-wish, that the motive power for the dream is furnished by the Unc., and, owing to this latter movement, we shall assume the unconscious system as the starting-point of the dream formation. This dream impulse, like all other thought structures, will now strive to continue itself in the foreconscious, and thence to gain admission to consciousness.

Experience teaches us that the road leading from the foreconscious to consciousness is closed to the dream thoughts during the day by the resistance of the censor. At night the dream thoughts gain admission to consciousness, but the question arises, in what way and because of what change. If this admission was rendered possible to the dream thoughts through the fact that the resistance watching on the boundary between the unconscious and foreconscious sinks at night, we should then get dreams in the material of our presentations which did not show the hallucinatory character which just now interests us.

The sinking of the censor between the two systems, Unc. and Forec., can explain to us only such dreams as “Autodidasker,” but not dreams like the one of the burning child, which we have taken as a problem at the outset in these present investigations.

What takes place in the hallucinatory dream we can describe in no other way than by saying that the excitement takes a retrogressive course. It takes its station, not at the motor end of the apparatus, but at the sensible end, and finally reaches the system of the perceptions. If we call the direction towards which the psychic process continues from the unconscious into the waking state the progressive, we may then speak of the dream as having a regressive character.

This regression is surely one of the most important peculiarities of the dream process; but we must not forget that it does not belong to the dream alone. The intentional recollection and other processes of our normal thinking also require a retrogression in the psychic apparatus from any complex presentation act to the raw material of the memory traces lying at its basis. But during the waking state this turning backward does not reach beyond the memory pictures; it is unable to produce the hallucinatory vividness of the perception pictures. Why is this different in the dream? When we spoke of the condensation work of the dream we could not avoid the assumption that the intensities adhering to the presentations are fully transferred from one to another through the dream-work. It is probably this modification of the former psychic process which makes possible the occupation of the system of P to its full sensual vividness in the opposite direction from thought.

I hope that we are far from deluding ourselves about the importance of this present discussion. We have done nothing more than give a name to an inexplicable phenomenon. We call it regression if the presentation in the dream is changed back to the perceptible image from which it once originated. But even this step demands justification. Why this naming, if it does not teach us anything new? I believe, however, that the name “Regression” will serve us to the extent of connecting a fact familiar to us with a scheme of the psychic apparatus which is supplied with a direction. At this point, for the first time, it is worth the trouble to construct such a scheme. For, with the help of this scheme, any other peculiarity of the dream formation will become clear to us without further reflection. If we look upon the dream as a process of regression in the assumed psychic apparatus, we can readily understand the empirically proven fact that all mental relation of the dream thoughts either is lost in the dream-work or can come to expression only with difficulty. According to our scheme, these mental relations are contained not in the first Mem-systems, but in those lying further to the front, and in the regression they must forfeit their expression in favour of the perception pictures. The structure of the dream thoughts is in the regression broken up into its raw material.

But what change renders possible this regression which is impossible during the day? Let us here be content with assumption. There must evidently be some alterations in the charge of energy belonging to the single systems causing the latter to become accessible or inaccessible to the discharge of the excitement; but in any such apparatus the same effect upon the course of excitement might be brought about through more than one form of such changes. This naturally reminds us of the state of sleep and of the many changes of energy this state produces at the sensible end of the apparatus. During the day there is a continuous coursing stream from the Ψ-system of the P toward the motility; this current ceases at night, and no longer hinders a streaming of the current of excitement in the opposite direction. This would appear to be that “seclusion from the outer world” which according to the theory of some authors is supposed to explain the psychological character of the dream (vide p. 30). In the explanation of the regression of the dream we shall, however, have to consider those other regressions which originate during morbid waking states. In these other forms the explanation just given plainly leaves us in the lurch. Regression takes place in spite of the uninterrupted sensible current in a progressive direction.

The hallucinations of hysteria and paranoia, as well as the visions of mentally normal persons, I can explain as actually corresponding to regressions, being in fact thoughts transformed into images; and only such thoughts are subjected to this transformation as are in intimate connection with suppressed or unconscious recollections. As an example I shall cite one of my youngest hysterical patients—a boy, twelve years old, who was prevented from falling asleep by “green faces with red eyes,” which terrified him. The source of this manifestation was the suppressed, but once conscious, memory of a boy whom he had often seen during four years, and who offered him a deterring example of many childish bad habits, including onanism, which now formed the subject of his own reproach. His mother had noticed at the time that the complexion of the ill-bred boy was greenish and that he had red (i.e. red bordered) eyes. Hence the terrible vision which constantly served to remind him of his mother’s warning that such boys become demented, that they are unable to make progress at school, and are doomed to an early death. A part of this prediction came true in the case of the little patient; he could not successfully pursue his high school studies, and, as appeared on examination of his involuntary fancies, he stood in great dread of the remainder of the prophecy. However, after a brief period of successful treatment, his sleep was restored, he lost his fears, and finished his scholastic year with an excellent record.

I may also add here the interpretation of a vision related to me by an hysteric forty years of age, as having occurred in her normal life. On opening her eyes one morning she beheld in the room her brother, whom she knew to be confined in an insane asylum. Her little son was asleep by her side. Lest the child should be frightened on seeing his uncle, and fall into convulsions, she pulled the sheet over the little one; this done, the phantom disappeared. This vision is the re-casting of one of her infantile reminiscences which, although conscious, is most intimately connected with all the unconscious material in her mind. Her nursemaid told her that her mother, who had died young (the patient was then only a year and a half old), had suffered from epileptic or hysterical convulsions, which dated back to a fright caused by her brother (the patient’s uncle), who appeared to her disguised as a spectre with a sheet over his head. The vision contains the same elements as the reminiscence, viz. the appearance of the brother, the sheet, the fright, and its effect. These elements, however, are ranged in different relations, and are transferred to other persons. The obvious motive of the vision, which replaces the idea, is her solicitude lest her little son, who bore a striking resemblance to his uncle, should share the latter’s fate. Both examples here cited are not entirely unrelated to sleep, and may therefore be unsuitable as proof for my assertion. I may therefore refer to my analysis of an hallucinatory paranoia,^[FP] and to the results of my hitherto unpublished studies on the psychology of the psychoneuroses in order to emphasize the fact that in these cases of regressive thought transformation one must not overlook the influence of a suppressed or unconscious reminiscence, this being in most cases of an infantile character. This recollection, so to speak, draws into the regression the thought with which it is connected, which is prevented from expression by the censor—that is, into that form of representation in which the recollection itself exists psychically. I may here mention as a result of my studies in hysteria that if we succeed in restoring infantile scenes to consciousness (whether recollections or fancies) they are seen as hallucinations, and are divested of this character only after reproduction. It is also known that the earliest infantile memories retain the character of perceptible vividness until late in life, even in persons who are otherwise not visual in memory.

If, now, we keep in mind what part is played in the dream thoughts by the infantile reminiscences or the phantasies based upon them, how often fragments of these reminiscences emerge in the dream content, and how often they even give origin to dream wishes, we cannot deny the probability that in the dream, too, the transformation of thoughts into visual images may be the result of the attraction exerted by the visually represented reminiscences, striving for reanimation, upon the thoughts severed from consciousness and struggling for expression. Following this conception, we may further describe the dream as a modified substitute for the infantile scene produced by transference to recent material. The infantile cannot enforce its renewal, and must therefore be satisfied to return as a dream.

This reference to the significance of the infantile scenes (or of their phantastic repetitions), as in a manner furnishing the pattern for the dream content, renders superfluous the assumption made by Scherner and his pupils, of an inner source of excitement. Scherner assumes a state of “visual excitation” of internal excitement in the organ of sight when the dreams manifest a particular vividness or a special abundance of visual elements. We need not object to this assumption, but may be satisfied with establishing such state of excitation for the psychic perceptive system of the organs of vision only; we shall, however, assert that this state of excitation is formed through the memory, and is merely a refreshing of the former actual visual excitation. I cannot, from my own experience, give a good example showing such an influence of infantile reminiscence; my own dreams are surely less rich in perceptible elements than I must fancy those of others; but in my most beautiful and most vivid dream of late years I can easily trace the hallucinatory distinctness of the dream contents to the sensuous nature of recently received impressions. On page 368 I mentioned a dream in which the dark blue colour of the water, the brown colour of the smoke issuing from the ship’s funnels, and the sombre brown and red of the buildings which I had seen made a profound and lasting impression on my mind. This dream, if any, must be attributed to visual excitation. But what has brought my visual organ into this excitable state? It was a recent impression uniting itself with a series of former ones. The colours I beheld were those of the toy blocks with which my children erected a grand structure for my admiration on the day preceding the dream. The same sombre red colour covered the large blocks and the same blue and brown the small ones. Connected with these were the colour impression of my last journey in Italy, the charming blue of the Isonzo and the Lagoon, the brown hue of the Alpine region. The beautiful colours seen in the dream were but a repetition of those seen in the memory.

Let us review what we have learned about this peculiarity which the dream has of transforming its content of ideas into plastic images. We have neither explained this character of the dream-work nor traced it to known laws of psychology, but we have singled it out as pointing to unknown connections, and designated it by the name of the “regredient” character. Wherever this regression has occurred, we have regarded it as an effect of the resistance which opposes the progress of the thought on its normal way to consciousness, as well as a result of the simultaneous attraction exerted upon it by the vivid memories present. Regression is perhaps facilitated in the dream by the cessation of the progressive stream running from the sense organs during the day. For this auxiliary moment there must be compensation in the other forms of regression through a fortifying of the other motives of regression. We must also bear in mind that in pathological cases of regression, as in the dream, the process of transference of energy must be different from that of the regressions of normal psychic life, as it renders possible a full hallucinatory occupation of the perception systems. What we have described in the analysis of the dream-work as “Regard for Dramatic Fitness” may be referred to the selective attraction of visually recollected scenes, touched by the dream thoughts.

It is quite possible that this first part of our psychological utilisation of the dream does not entirely satisfy even us. We must, however, console ourselves with the fact that we are compelled to build in the dark. If we have not altogether strayed from the right path, we shall be sure to reach about the same ground from another starting-point, and thereafter perhaps be better able to see our way.

(c) The Wish-Fulfilment.

The dream of the burning child cited above affords us a welcome opportunity for appreciating the difficulties confronting the theory of wish-fulfilment. That the dream should be nothing but a wish-fulfilment surely seemed strange to us all—and that not alone because of the contradictions offered by the anxiety dream.

After learning from the first analytical explanations that the dream conceals sense and psychic validity, we could hardly expect so simple a determination of this sense. According to the correct but concise definition of Aristotle, the dream is a continuation of thinking in sleep (in so far as one sleeps). Considering that during the day our thoughts produce such a diversity of psychic acts—judgments, conclusions, contradictions, expectations, intentions, &c.—why should our sleeping thoughts be forced to confine themselves to the production of wishes? Are there not, on the contrary, many dreams that present a different psychic act in dream form, e.g., a solicitude, and is not the very transparent father’s dream mentioned above of just such a nature? From the gleam of light falling into his eyes while asleep the father draws the solicitous conclusion that a candle has been upset and may have set fire to the corpse; he transforms this conclusion into a dream by investing it with a senseful situation enacted in the present tense. What part is played in this dream by the wish-fulfilment, and which are we to suspect—the predominance of the thought continued from the waking state or of the thought incited by the new sensory impression?

All these considerations are just, and force us to enter more deeply into the part played by the wish-fulfilment in the dream, and into the significance of the waking thoughts continued in sleep.

It is in fact the wish-fulfilment that has already induced us to separate dreams into two groups. We have found some dreams that were plainly wish-fulfilments; and others in which wish-fulfilment could not be recognised, and was frequently concealed by every available means. In this latter class of dreams we recognised the influence of the dream censor. The undisguised wish dreams were chiefly found in children, yet fleeting open-hearted wish dreams seemed (I purposely emphasize this word) to occur also in adults.

We may now ask whence the wish fulfilled in the dream originates. But to what opposition or to what diversity do we refer this “whence”? I think it is to the opposition between conscious daily life and a psychic activity remaining unconscious which can only make itself noticeable during the night. I thus find a threefold possibility for the origin of a wish. Firstly, it may have been incited during the day, and owing to external circumstances failed to find gratification, there is thus left for the night an acknowledged but unfulfilled wish. Secondly, it may come to the surface during the day but be rejected, leaving an unfulfilled but suppressed wish. Or, thirdly, it may have no relation to daily life, and belong to those wishes that originate during the night from the suppression. If we now follow our scheme of the psychic apparatus, we can localise a wish of the first order in the system Forec. We may assume that a wish of the second order has been forced back from the Forec. system into the Unc. system, where alone, if anywhere, it can maintain itself; while a wish-feeling of the third order we consider altogether incapable of leaving the Unc. system. This brings up the question whether wishes arising from these different sources possess the same value for the dream, and whether they have the same power to incite a dream.

On reviewing the dreams which we have at our disposal for answering this question, we are at once moved to add as a fourth source of the dream-wish the actual wish incitements arising during the night, such as thirst and sexual desire. It then becomes evident that the source of the dream-wish does not affect its capacity to incite a dream. This view is supported by the dream of the little girl who continued the sea trip interrupted during the day, and by the other children’s dreams referred to; they are explained by an unfulfilled but not suppressed wish from the day-time. That a wish suppressed during the day asserts itself in the dream can be shown by a great many examples. I shall mention a very simple example of this class. A somewhat sarcastic young lady, whose younger friend has become engaged to be married, is asked throughout the day by her acquaintances whether she knows and what she thinks of the fiancé. She answers with unqualified praise, thereby silencing her own judgment, as she would prefer to tell the truth, namely, that he is an ordinary person (Dutzendmensch).^[FQ] The following night she dreams that the same question is put to her, and that she replies with the formula: “In case of subsequent orders it will suffice to mention the number.” Finally, we have learned from numerous analyses that the wish in all dreams that have been subject to distortion has been derived from the unconscious, and has been unable to come to perception in the waking state. Thus it would appear that all wishes are of the same value and force for the dream formation.

I am at present unable to prove that the state of affairs is really different, but I am strongly inclined to assume a more stringent determination of the dream-wish. Children’s dreams leave no doubt that an unfulfilled wish of the day may be the instigator of the dream. But we must not forget that it is, after all, the wish of a child, that it is a wish-feeling of infantile strength only. I have a strong doubt whether an unfulfilled wish from the day would suffice to create a dream in an adult. It would rather seem that as we learn to control our impulses by intellectual activity, we more and more reject as vain the formation or retention of such intense wishes as are natural to childhood. In this, indeed, there may be individual variations; some retain the infantile type of psychic processes longer than others. The differences are here the same as those found in the gradual decline of the originally distinct visual imagination.

In general, however, I am of the opinion that unfulfilled wishes of the day are insufficient to produce a dream in adults. I readily admit that the wish instigators originating in conscious life contribute towards the incitement of dreams, but that is probably all. The dream would not originate if the foreconscious wish were not reinforced from another source.

That source is the unconscious. I believe that the conscious wish is a dream inciter only if it succeeds in arousing a similar unconscious wish which reinforces it. Following the suggestions obtained through the psychoanalysis of the neuroses, I believe that these unconscious wishes are always active and ready for expression whenever they find an opportunity to unite themselves with an emotion from conscious life, and that they transfer their greater intensity to the lesser intensity of the latter.^[FR] It may therefore seem that the conscious wish alone has been realised in a dream; but a slight peculiarity in the formation of this dream will put us on the track of the powerful helper from the unconscious. These ever active and, as it were, immortal wishes from the unconscious recall the legendary Titans who from time immemorial have borne the ponderous mountains which were once rolled upon them by the victorious gods, and which even now quiver from time to time from the convulsions of their mighty limbs; I say that these wishes found in the repression are of themselves of an infantile origin, as we have learned from the psychological investigation of the neuroses. I should like, therefore, to withdraw the opinion previously expressed that it is unimportant whence the dream-wish originates, and replace it by another, as follows: The wish manifested in the dream must be an infantile one. In the adult it originates in the Unc., while in the child, where no separation and censor as yet exist between Forec. and Unc., or where these are only in the process of formation, it is an unfulfilled and unrepressed wish from the waking state. I am aware that this conception cannot be generally demonstrated, but I maintain nevertheless that it can be frequently demonstrated, even where it was not suspected, and that it cannot be generally refuted.

The wish-feelings which remain from the conscious waking state are, therefore, relegated to the background in the dream formation. In the dream content I shall attribute to them only the part attributed to the material of actual sensations during sleep (see p. 185). If I now take into account those other psychic instigations remaining from the waking state which are not wishes, I shall only adhere to the line mapped out for me by this train of thought. We may succeed in provisionally terminating the sum of energy of our waking thoughts by deciding to go to sleep. He is a good sleeper who can do this; Napoleon I. is reputed to have been a model of this sort. But we do not always succeed in accomplishing it, or in accomplishing it perfectly. Unsolved problems, harassing cares, overwhelming impressions continue the thinking activity even during sleep, maintaining psychic processes in the system which we have termed the foreconscious. These mental processes continuing into sleep may be divided into the following groups: 1, That which has not been terminated during the day owing to casual prevention; 2, that which has been left unfinished by temporary paralysis of our mental power, i.e. the unsolved; 3, that which has been rejected and suppressed during the day. This unites with a powerful group (4) formed by that which has been excited in our Unc. during the day by the work of the foreconscious. Finally, we may add group (5) consisting of the indifferent and hence unsettled impressions of the day.

We should not underrate the psychic intensities introduced into sleep by these remnants of waking life, especially those emanating from the group of the unsolved. These excitations surely continue to strive for expression during the night, and we may assume with equal certainty that the sleeping state renders impossible the usual continuation of the excitement in the foreconscious and the termination of the excitement by its becoming conscious. As far as we can normally become conscious of our mental processes, even during the night, in so far we are not asleep. I shall not venture to state what change is produced in the Forec. system by the sleeping state, but there is no doubt that the psychological character of sleep is essentially due to the change of energy in this very system, which also dominates the approach to motility, which is paralysed during sleep. In contradistinction to this, there seems to be nothing in the psychology of the dream to warrant the assumption that sleep produces any but secondary changes in the conditions of the Unc. system. Hence, for the nocturnal excitation in the Forec. there remains no other path than that followed by the wish excitements from the Unc. This excitation must seek reinforcement from the Unc., and follow the detours of the unconscious excitations. But what is the relation of the foreconscious day remnants to the dream? There is no doubt that they penetrate abundantly into the dream, that they utilise the dream content to obtrude themselves upon consciousness even during the night; indeed, they occasionally even dominate the dream content, and impel it to continue the work of the day; it is also certain that the day remnants may just as well have any other character as that of wishes; but it is highly instructive and even decisive for the theory of wish-fulfilment to see what conditions they must comply with in order to be received into the dream.

Let us pick out one of the dreams cited above as examples, e.g., the dream in which my friend Otto seems to show the symptoms of Basedow’s disease (p. 228). My friend Otto’s appearance occasioned me some concern during the day, and this worry, like everything else referring to this person, affected me. I may also assume that these feelings followed me into sleep. I was probably bent on finding out what was the matter with him. In the night my worry found expression in the dream which I have reported, the content of which was not only senseless, but failed to show any wish-fulfilment. But I began to investigate for the source of this incongruous expression of the solicitude felt during the day, and analysis revealed the connection. I identified my friend Otto with a certain Baron L. and myself with a Professor R. There was only one explanation for my being impelled to select just this substitution for the day thought. I must have always been prepared in the Unc. to identify myself with Professor R., as it meant the realisation of one of the immortal infantile wishes, viz. that of becoming great. Repulsive ideas respecting my friend, that would certainly have been repudiated in a waking state, took advantage of the opportunity to creep into the dream, but the worry of the day likewise found some form of expression through a substitution in the dream content. The day thought, which was no wish in itself but rather a worry, had in some way to find a connection with the infantile now unconscious and suppressed wish, which then allowed it, though already properly prepared, to “originate” for consciousness. The more dominating this worry, the stronger must be the connection to be established; between the contents of the wish and that of the worry there need be no connection, nor was there one in any of our examples.

We can now sharply define the significance of the unconscious wish for the dream. It may be admitted that there is a whole class of dreams in which the incitement originates preponderatingly or even exclusively from the remnants of daily life; and I believe that even my cherished desire to become at some future time a “professor extraordinarius” would have allowed me to slumber undisturbed that night had not my worry about my friend’s health been still active. But this worry alone would not have produced a dream; the motive power needed by the dream had to be contributed by a wish, and it was the affair of the worriment to procure for itself such wish as a motive power of the dream. To speak figuratively, it is quite possible that a day thought plays the part of the contractor (entrepreneur) in the dream. But it is known that no matter what idea the contractor may have in mind, and how desirous he may be of putting it into operation, he can do nothing without capital; he must depend upon a capitalist to defray the necessary expenses, and this capitalist, who supplies the psychic expenditure for the dream is invariably and indisputably a wish from the unconscious, no matter what the nature of the waking thought may be.

In other cases the capitalist himself is the contractor for the dream; this, indeed, seems to be the more usual case. An unconscious wish is produced by the day’s work, which in turn creates the dream. The dream processes, moreover, run parallel with all the other possibilities of the economic relationship used here as an illustration. Thus, the entrepreneur may contribute some capital himself, or several entrepreneurs may seek the aid of the same capitalist, or several capitalists may jointly supply the capital required by the entrepreneur. Thus there are dreams produced by more than one dream-wish, and many similar variations which may readily be passed over and are of no further interest to us. What we have left unfinished in this discussion of the dream-wish we shall be able to develop later.

The “tertium comparationis” in the comparisons just employed—i.e. the sum placed at our free disposal in proper allotment—admits of still finer application for the illustration of the dream structure. As shown on p. 285 we can recognise in most dreams a centre especially supplied with perceptible intensity. This is regularly the direct representation of the wish-fulfilment; for, if we undo the displacements of the dream-work by a process of retrogression, we find that the psychic intensity of the elements in the dream thoughts is replaced by the perceptible intensity of the elements in the dream content. The elements adjoining the wish-fulfilment have frequently nothing to do with its sense, but prove to be descendants of painful thoughts which oppose the wish. But, owing to their frequently artificial connection with the central element, they have acquired sufficient intensity to enable them to come to expression. Thus, the force of expression of the wish-fulfilment is diffused over a certain sphere of association, within which it raises to expression all elements, including those that are in themselves impotent. In dreams having several strong wishes we can readily separate from one another the spheres of the individual wish-fulfilments; the gaps in the dream likewise can often be explained as boundary zones.

Although the foregoing remarks have considerably limited the significance of the day remnants for the dream, it will nevertheless be worth our while to give them some attention. For they must be a necessary ingredient in the formation of the dream, inasmuch as experience reveals the surprising fact that every dream shows in its content a connection with some impression of a recent day, often of the most indifferent kind. So far we have failed to see any necessity for this addition to the dream mixture (p. 153). This necessity appears only when we follow closely the part played by the unconscious wish, and then seek information in the psychology of the neuroses. We thus learn that the unconscious idea, as such, is altogether incapable of entering into the foreconscious, and that it can exert an influence there only by uniting with a harmless idea already belonging to the foreconscious, to which it transfers its intensity and under which it allows itself to be concealed. This is the fact of transference which furnishes an explanation for so many surprising occurrences in the psychic life of neurotics.

The idea from the foreconscious which thus obtains an unmerited abundance of intensity may be left unchanged by the transference, or it may have forced upon it a modification from the content of the transferring idea. I trust the reader will pardon my fondness for comparisons from daily life, but I feel tempted to say that the relations existing for the repressed idea are similar to the situations existing in Austria for the American dentist, who is forbidden to practise unless he gets permission from a regular physician to use his name on the public signboard and thus cover the legal requirements. Moreover, just as it is naturally not the busiest physicians who form such alliances with dental practitioners, so in the psychic life only such foreconscious or conscious ideas are chosen to cover a repressed idea as have not themselves attracted much of the attention which is operative in the foreconscious. The unconscious entangles with its connections preferentially either those impressions and ideas of the foreconscious which have been left unnoticed as indifferent, or those that have soon been deprived of this attention through rejection. It is a familiar fact from the association studies confirmed by every experience, that ideas which have formed intimate connections in one direction assume an almost negative attitude to whole groups of new connections. I once tried from this principle to develop a theory for hysterical paralysis.

If we assume that the same need for the transference of the repressed ideas which we have learned to know from the analysis of the neuroses makes its influence felt in the dream as well, we can at once explain two riddles of the dream, viz. that every dream analysis shows an interweaving of a recent impression, and that this recent element is frequently of the most indifferent character. We may add what we have already learned elsewhere, that these recent and indifferent elements come so frequently into the dream content as a substitute for the most deep-lying of the dream thoughts, for the further reason that they have least to fear from the resisting censor. But while this freedom from censorship explains only the preference for trivial elements, the constant presence of recent elements points to the fact that there is a need for transference. Both groups of impressions satisfy the demand of the repression for material still free from associations, the indifferent ones because they have offered no inducement for extensive associations, and the recent ones because they have had insufficient time to form such associations.

We thus see that the day remnants, among which we may now include the indifferent impressions when they participate in the dream formation, not only borrow from the Unc. the motive power at the disposal of the repressed wish, but also offer to the unconscious something indispensable, namely, the attachment necessary to the transference. If we here attempted to penetrate more deeply into the psychic processes, we should first have to throw more light on the play of emotions between the foreconscious and the unconscious, to which, indeed, we are urged by the study of the psychoneuroses, whereas the dream itself offers no assistance in this respect.

Just one further remark about the day remnants. There is no doubt that they are the actual disturbers of sleep, and not the dream, which, on the contrary, strives to guard sleep. But we shall return to this point later.

We have so far discussed the dream-wish, we have traced it to the sphere of the Unc., and analysed its relations to the day remnants, which in turn may be either wishes, psychic emotions of any other kind, or simply recent impressions. We have thus made room for any claims that may be made for the importance of conscious thought activity in dream formations in all its variations. Relying upon our thought series, it would not be at all impossible for us to explain even those extreme cases in which the dream as a continuer of the day work brings to a happy conclusion an unsolved problem of the waking state. We do not, however, possess an example, the analysis of which might reveal the infantile or repressed wish source furnishing such alliance and successful strengthening of the efforts of the foreconscious activity. But we have not come one step nearer a solution of the riddle: Why can the unconscious furnish the motive power for the wish-fulfilment only during sleep? The answer to this question must throw light on the psychic nature of wishes; and it will be given with the aid of the diagram of the psychic apparatus.

We do not doubt that even this apparatus attained its present perfection through a long course of development. Let us attempt to restore it as it existed in an early phase of its activity. From assumptions, to be confirmed elsewhere, we know that at first the apparatus strove to keep as free from excitement as possible, and in its first formation, therefore, the scheme took the form of a reflex apparatus, which enabled it promptly to discharge through the motor tracts any sensible stimulus reaching it from without. But this simple function was disturbed by the wants of life, which likewise furnish the impulse for the further development of the apparatus. The wants of life first manifested themselves to it in the form of the great physical needs. The excitement aroused by the inner want seeks an outlet in motility, which may be designated as “inner changes” or as an “expression of the emotions.” The hungry child cries or fidgets helplessly, but its situation remains unchanged; for the excitation proceeding from an inner want requires, not a momentary outbreak, but a force working continuously. A change can occur only if in some way a feeling of gratification is experienced—which in the case of the child must be through outside help—in order to remove the inner excitement. An essential constituent of this experience is the appearance of a certain perception (of food in our example), the memory picture of which thereafter remains associated with the memory trace of the excitation of want.

Thanks to the established connection, there results at the next appearance of this want a psychic feeling which revives the memory picture of the former perception, and thus recalls the former perception itself, i.e. it actually re-establishes the situation of the first gratification. We call such a feeling a wish; the reappearance of the perception constitutes the wish-fulfilment, and the full revival of the perception by the want excitement constitutes the shortest road to the wish-fulfilment. We may assume a primitive condition of the psychic apparatus in which this road is really followed, i.e. where the wishing merges into an hallucination. This first psychic activity therefore aims at an identity of perception, i.e. it aims at a repetition of that perception which is connected with the fulfilment of the want.

This primitive mental activity must have been modified by bitter practical experience into a more expedient secondary activity. The establishment of the identity perception on the short regressive road within the apparatus does not in another respect carry with it the result which inevitably follows the revival of the same perception from without. The gratification does not take place, and the want continues. In order to equalise the internal with the external sum of energy, the former must be continually maintained, just as actually happens in the hallucinatory psychoses and in the deliriums of hunger which exhaust their psychic capacity in clinging to the object desired. In order to make more appropriate use of the psychic force, it becomes necessary to inhibit the full regression so as to prevent it from extending beyond the image of memory, whence it can select other paths leading ultimately to the establishment of the desired identity from the outer world. This inhibition and consequent deviation from the excitation becomes the task of a second system which dominates the voluntary motility, i.e. through whose activity the expenditure of motility is now devoted to previously recalled purposes. But this entire complicated mental activity which works its way from the memory picture to the establishment of the perception identity from the outer world merely represents a detour which has been forced upon the wish-fulfilment by experience.^[FS] Thinking is indeed nothing but the equivalent of the hallucinatory wish; and if the dream be called a wish-fulfilment this becomes self-evident, as nothing but a wish can impel our psychic apparatus to activity. The dream, which in fulfilling its wishes follows the short regressive path, thereby preserves for us only an example of the primary form of the psychic apparatus which has been abandoned as inexpedient. What once ruled in the waking state when the psychic life was still young and unfit seems to have been banished into the sleeping state, just as we see again in the nursery the bow and arrow, the discarded primitive weapons of grown-up humanity. The dream is a fragment of the abandoned psychic life of the child. In the psychoses these modes of operation of the psychic apparatus, which are normally suppressed in the waking state, reassert themselves, and then betray their inability to satisfy our wants in the outer world.

The unconscious wish-feelings evidently strive to assert themselves during the day also, and the fact of transference and the psychoses teach us that they endeavour to penetrate to consciousness and dominate motility by the road leading through the system of the foreconscious. It is, therefore, the censor lying between the Unc. and the Forec., the assumption of which is forced upon us by the dream, that we have to recognise and honour as the guardian of our psychic health. But is it not carelessness on the part of this guardian to diminish its vigilance during the night and to allow the suppressed emotions of the Unc. to come to expression, thus again making possible the hallucinatory regression? I think not, for when the critical guardian goes to rest—and we have proof that his slumber is not profound—he takes care to close the gate to motility. No matter what feelings from the otherwise inhibited Unc. may roam about on the scene, they need not be interfered with; they remain harmless because they are unable to put in motion the motor apparatus which alone can exert a modifying influence upon the outer world. Sleep guarantees the security of the fortress which is under guard. Conditions are less harmless when a displacement of forces is produced, not through a nocturnal diminution in the operation of the critical censor, but through pathological enfeeblement of the latter or through pathological reinforcement of the unconscious excitations, and this while the foreconscious is charged with energy and the avenues to motility are open. The guardian is then overpowered, the unconscious excitations subdue the Forec.; through it they dominate our speech and actions, or they enforce the hallucinatory regression, thus governing an apparatus not designed for them by virtue of the attraction exerted by the perceptions on the distribution of our psychic energy. We call this condition a psychosis.

We are now in the best position to complete our psychological construction, which has been interrupted by the introduction of the two systems, Unc. and Forec. We have still, however, ample reason for giving further consideration to the wish as the sole psychic motive power in the dream. We have explained that the reason why the dream is in every case a wish realisation is because it is a product of the Unc., which knows no other aim in its activity but the fulfilment of wishes, and which has no other forces at its disposal but wish-feelings. If we avail ourselves for a moment longer of the right to elaborate from the dream interpretation such far-reaching psychological speculations, we are in duty bound to demonstrate that we are thereby bringing the dream into a relationship which may also comprise other psychic structures. If there exists a system of the Unc.—or something sufficiently analogous to it for the purpose of our discussion—the dream cannot be its sole manifestation; every dream may be a wish-fulfilment, but there must be other forms of abnormal wish-fulfilment besides this of dreams. Indeed, the theory of all psychoneurotic symptoms culminates in the proposition that they too must be taken as wish-fulfilments of the unconscious. Our explanation makes the dream only the first member of a group most important for the psychiatrist, an understanding of which means the solution of the purely psychological part of the psychiatric problem. But other members of this group of wish-fulfilments, e.g., the hysterical symptoms, evince one essential quality which I have so far failed to find in the dream. Thus, from the investigations frequently referred to in this treatise, I know that the formation of an hysterical symptom necessitates the combination of both streams of our psychic life. The symptom is not merely the expression of a realised unconscious wish, but it must be joined by another wish from the foreconscious which is fulfilled by the same symptom; so that the symptom is at least doubly determined, once by each one of the conflicting systems. Just as in the dream, there is no limit to further over-determination. The determination not derived from the Unc. is, as far as I can see, invariably a stream of thought in reaction against the unconscious wish, e.g., a self-punishment. Hence I may say, in general, that an hysterical symptom originates only where two contrasting wish-fulfilments, having their source in different psychic systems, are able to combine in one expression. (Compare my latest formulation of the origin of the hysterical symptoms in a treatise published by the Zeitschrift für Sexualwissenschaft, by Hirschfeld and others, 1908). Examples on this point would prove of little value, as nothing but a complete unveiling of the complication in question would carry conviction. I therefore content myself with the mere assertion, and will cite an example, not for conviction but for explication. The hysterical vomiting of a female patient proved, on the one hand, to be the realisation of an unconscious fancy from the time of puberty, that she might be continuously pregnant and have a multitude of children, and this was subsequently united with the wish that she might have them from as many men as possible. Against this immoderate wish there arose a powerful defensive impulse. But as the vomiting might spoil the patient’s figure and beauty, so that she would not find favour in the eyes of mankind, the symptom was therefore in keeping with her punitive trend of thought, and, being thus admissible from both sides, it was allowed to become a reality. This is the same manner of consenting to a wish-fulfilment which the queen of the Parthians chose for the triumvir Crassus. Believing that he had undertaken the campaign out of greed for gold, she caused molten gold to be poured into the throat of the corpse. “Now hast thou what thou hast longed for.” As yet we know of the dream only that it expresses a wish-fulfilment of the unconscious; and apparently the dominating foreconscious permits this only after it has subjected the wish to some distortions. We are really in no position to demonstrate regularly a stream of thought antagonistic to the dream-wish which is realised in the dream as in its counterpart. Only now and then have we found in the dream traces of reaction formations, as, for instance, the tenderness toward friend R. in the “uncle dream” (p. 116). But the contribution from the foreconscious, which is missing here, may be found in another place. While the dominating system has withdrawn on the wish to sleep, the dream may bring to expression with manifold distortions a wish from the Unc., and realise this wish by producing the necessary changes of energy in the psychic apparatus, and may finally retain it through the entire duration of sleep.^[FT]

This persistent wish to sleep on the part of the foreconscious in general facilitates the formation of the dream. Let us refer to the dream of the father who, by the gleam of light from the death chamber, was brought to the conclusion that the body has been set on fire. We have shown that one of the psychic forces decisive in causing the father to form this conclusion, instead of being awakened by the gleam of light, was the wish to prolong the life of the child seen in the dream by one moment. Other wishes proceeding from the repression probably escape us, because we are unable to analyse this dream. But as a second motive power of the dream we may mention the father’s desire to sleep, for, like the life of the child, the sleep of the father is prolonged for a moment by the dream. The underlying motive is: “Let the dream go on, otherwise I must wake up.” As in this dream so also in all other dreams, the wish to sleep lends its support to the unconscious wish. On page 104 we reported dreams which were apparently dreams of convenience. But, properly speaking, all dreams may claim this designation. The efficacy of the wish to continue to sleep is the most easily recognised in the waking dreams, which so transform the objective sensory stimulus as to render it compatible with the continuance of sleep; they interweave this stimulus with the dream in order to rob it of any claims it might make as a warning to the outer world. But this wish to continue to sleep must also participate in the formation of all other dreams which may disturb the sleeping state from within only. “Now, then, sleep on; why, it’s but a dream”; this is in many cases the suggestion of the Forec. to consciousness when the dream goes too far; and this also describes in a general way the attitude of our dominating psychic activity toward dreaming, though the thought remains tacit. I must draw the conclusion that throughout our entire sleeping state we are just as certain that we are dreaming as we are certain that we are sleeping. We are compelled to disregard the objection urged against this conclusion that our consciousness is never directed to a knowledge of the former, and that it is directed to a knowledge of the latter only on special occasions when the censor is unexpectedly surprised. Against this objection we may say that there are persons who are entirely conscious of their sleeping and dreaming, and who are apparently endowed with the conscious faculty of guiding their dream life. Such a dreamer, when dissatisfied with the course taken by the dream, breaks it off without awakening, and begins it anew in order to continue it with a different turn, like the popular author who, on request, gives a happier ending to his play. Or, at another time, if placed by the dream in a sexually exciting situation, he thinks in his sleep: “I do not care to continue this dream and exhaust myself by a pollution; I prefer to defer it in favour of a real situation.”

(d) Waking caused by the Dream—The Function of the Dream—The Anxiety Dream.

Since we know that the foreconscious is suspended during the night by the wish to sleep, we can proceed to an intelligent investigation of the dream process. But let us first sum up the knowledge of this process already gained. We have shown that the waking activity leaves day remnants from which the sum of energy cannot be entirely removed; or the waking activity revives during the day one of the unconscious wishes; or both conditions occur simultaneously; we have already discovered the many variations that may take place. The unconscious wish has already made its way to the day remnants, either during the day or at any rate with the beginning of sleep, and has effected a transference to it. This produces a wish transferred to the recent material, or the suppressed recent wish comes to life again through a reinforcement from the unconscious. This wish now endeavours to make its way to consciousness on the normal path of the mental processes through the foreconscious, to which indeed it belongs through one of its constituent elements. It is confronted, however, by the censor, which is still active, and to the influence of which it now succumbs. It now takes on the distortion for which the way has already been paved by its transference to the recent material. Thus far it is in the way of becoming something resembling an obsession, delusion, or the like, i.e. a thought reinforced by a transference and distorted in expression by the censor. But its further progress is now checked through the dormant state of the foreconscious; this system has apparently protected itself against invasion by diminishing its excitements. The dream process, therefore, takes the regressive course, which has just been opened by the peculiarity of the sleeping state, and thereby follows the attraction exerted on it by the memory groups, which themselves exist in part only as visual energy not yet translated into terms of the later systems. On its way to regression the dream takes on the form of dramatisation. The subject of compression will be discussed later. The dream process has now terminated the second part of its repeatedly impeded course. The first part expended itself progressively from the unconscious scenes or phantasies to the foreconscious, while the second part gravitates from the advent of the censor back to the perceptions. But when the dream process becomes a content of perception it has, so to speak, eluded the obstacle set up in the Forec. by the censor and by the sleeping state. It succeeds in drawing attention to itself and in being noticed by consciousness. For consciousness, which means to us a sensory organ for the reception of psychic qualities, may receive stimuli from two sources—first, from the periphery of the entire apparatus, viz. from the perception system, and, secondly, from the pleasure and pain stimuli, which constitute the sole psychic quality produced in the transformation of energy within the apparatus. All other processes in the Ψ-system, even those in the foreconscious, are devoid of any psychic quality, and are therefore not objects of consciousness inasmuch as they do not furnish pleasure or pain for perception. We shall have to assume that those liberations of pleasure and pain automatically regulate the outlet of the occupation processes. But in order to make possible more delicate functions, it was later found necessary to render the course of the presentations more independent of the manifestations of pain. To accomplish this the Forec. system needed some qualities of its own which could attract consciousness, and most probably received them through the connection of the foreconscious processes with the memory system of the signs of speech, which is not devoid of qualities. Through the qualities of this system, consciousness, which had hitherto been a sensory organ only for the perceptions, now becomes also a sensory organ for a part of our mental processes. Thus we have now, as it were, two sensory surfaces, one directed to perceptions and the other to the foreconscious mental processes.

I must assume that the sensory surface of consciousness devoted to the Forec. is rendered less excitable by sleep than that directed to the P-systems. The giving up of interest for the nocturnal mental processes is indeed purposeful. Nothing is to disturb the mind; the Forec. wants to sleep. But once the dream becomes a perception, it is then capable of exciting consciousness through the qualities thus gained. The sensory stimulus accomplishes what it was really destined for, namely, it directs a part of the energy at the disposal of the Forec. in the form of attention upon the stimulant. We must, therefore, admit that the dream invariably awakens us, that is, it puts into activity a part of the dormant force of the Forec. This force imparts to the dream that influence which we have designated as secondary elaboration for the sake of connection and comprehensibility. This means that the dream is treated by it like any other content of perception; it is subjected to the same ideas of expectation, as far at least as the material admits. As far as the direction is concerned in this third part of the dream, it may be said that here again the movement is progressive.

To avoid misunderstanding, it will not be amiss to say a few words about the temporal peculiarities of these dream processes. In a very interesting discussion, apparently suggested by Maury’s puzzling guillotine dream, Goblot^[29] tries to demonstrate that the dream requires no other time than the transition period between sleeping and awakening. The awakening requires time, as the dream takes place during that period. One is inclined to believe that the final picture of the dream is so strong that it forces the dreamer to awaken; but, as a matter of fact, this picture is strong only because the dreamer is already very near awakening when it appears. “Un rêve c’est un réveil qui commence.”

It has already been emphasized by Dugas^[18] that Goblot was forced to repudiate many facts in order to generalise his theory. There are, moreover, dreams from which we do not awaken, e.g., some dreams in which we dream that we dream. From our knowledge of the dream-work, we can by no means admit that it extends only over the period of awakening. On the contrary, we must consider it probable that the first part of the dream-work begins during the day when we are still under the domination of the foreconscious. The second phase of the dream-work, viz. the modification through the censor, the attraction by the unconscious scenes, and the penetration to perception must continue throughout the night. And we are probably always right when we assert that we feel as though we had been dreaming the whole night, although we cannot say what. I do not, however, think it necessary to assume that, up to the time of becoming conscious, the dream processes really follow the temporal sequence which we have described, viz. that there is first the transferred dream-wish, then the distortion of the censor, and consequently the change of direction to regression, and so on. We were forced to form such a succession for the sake of description; in reality, however, it is much rather a matter of simultaneously trying this path and that, and of emotions fluctuating to and fro, until finally, owing to the most expedient distribution, one particular grouping is secured which remains. From certain personal experiences, I am myself inclined to believe that the dream-work often requires more than one day and one night to produce its result; if this be true, the extraordinary art manifested in the construction of the dream loses all its marvels. In my opinion, even the regard for comprehensibility as an occurrence of perception may take effect before the dream attracts consciousness to itself. To be sure, from now on the process is accelerated, as the dream is henceforth subjected to the same treatment as any other perception. It is like fireworks, which require hours of preparation and only a moment for ignition.

Through the dream-work the dream process now gains either sufficient intensity to attract consciousness to itself and arouse the foreconscious, which is quite independent of the time or profundity of sleep, or, its intensity being insufficient it must wait until it meets the attention which is set in motion immediately before awakening. Most dreams seem to operate with relatively slight psychic intensities, for they wait for the awakening. This, however, explains the fact that we regularly perceive something dreamt on being suddenly aroused from a sound sleep. Here, as well as in spontaneous awakening, the first glance strikes the perception content created by the dream-work, while the next strikes the one produced from without.

But of greater theoretical interest are those dreams which are capable of waking us in the midst of sleep. We must bear in mind the expediency elsewhere universally demonstrated, and ask ourselves why the dream or the unconscious wish has the power to disturb sleep, i.e. the fulfilment of the foreconscious wish. This is probably due to certain relations of energy into which we have no insight. If we possessed such insight we should probably find that the freedom given to the dream and the expenditure of a certain amount of detached attention represent for the dream an economy in energy, keeping in view the fact that the unconscious must be held in check at night just as during the day. We know from experience that the dream, even if it interrupts sleep, repeatedly during the same night, still remains compatible with sleep. We wake up for an instant, and immediately resume our sleep. It is like driving off a fly during sleep, we awake ad hoc, and when we resume our sleep we have removed the disturbance. As demonstrated by familiar examples from the sleep of wet nurses, &c., the fulfilment of the wish to sleep is quite compatible with the retention of a certain amount of attention in a given direction.

But we must here take cognisance of an objection that is based on a better knowledge of the unconscious processes. Although we have ourselves described the unconscious wishes as always active, we have, nevertheless, asserted that they are not sufficiently strong during the day to make themselves perceptible. But when we sleep, and the unconscious wish has shown its power to form a dream, and with it to awaken the foreconscious, why, then, does this power become exhausted after the dream has been taken cognisance of? Would it not seem more probable that the dream should continually renew itself, like the troublesome fly which, when driven away, takes pleasure in returning again and again? What justifies our assertion that the dream removes the disturbance of sleep?

That the unconscious wishes always remain active is quite true. They represent paths which are passable whenever a sum of excitement makes use of them. Moreover, a remarkable peculiarity of the unconscious processes is the fact that they remain indestructible. Nothing can be brought to an end in the unconscious; nothing can cease or be forgotten. This impression is most strongly gained in the study of the neuroses, especially of hysteria. The unconscious stream of thought which leads to the discharge through an attack becomes passable again as soon as there is an accumulation of a sufficient amount of excitement. The mortification brought on thirty years ago, after having gained access to the unconscious affective source, operates during all these thirty years like a recent one. Whenever its memory is touched, it is revived and shows itself to be supplied with the excitement which is discharged in a motor attack. It is just here that the office of psychotherapy begins, its task being to bring about adjustment and forgetfulness for the unconscious processes. Indeed, the fading of memories and the flagging of affects, which we are apt to take as self-evident and to explain as a primary influence of time on the psychic memories, are in reality secondary changes brought about by painstaking work. It is the foreconscious that accomplishes this work; and the only course to be pursued by psychotherapy is to subjugate the Unc. to the domination of the Forec.

There are, therefore, two exits for the individual unconscious emotional process. It is either left to itself, in which case it ultimately breaks through somewhere and secures for once a discharge for its excitation into motility; or it succumbs to the influence of the foreconscious, and its excitation becomes confined through this influence instead of being discharged. It is the latter process that occurs in the dream. Owing to the fact that it is directed by the conscious excitement, the energy from the Forec., which confronts the dream when grown to perception, restricts the unconscious excitement of the dream and renders it harmless as a disturbing factor. When the dreamer wakes up for a moment, he has actually chased away the fly that has threatened to disturb his sleep. We can now understand that it is really more expedient and economical to give full sway to the unconscious wish, and clear its way to regression so that it may form a dream, and then restrict and adjust this dream by means of a small expenditure of foreconscious labour, than to curb the unconscious throughout the entire period of sleep. We should, indeed, expect that the dream, even if it was not originally an expedient process, would have acquired some function in the play of forces of the psychic life. We now see what this function is. The dream has taken it upon itself to bring the liberated excitement of the Unc. back under the domination of the foreconscious; it thus affords relief for the excitement of the Unc. and acts as a safety-valve for the latter, and at the same time it insures the sleep of the foreconscious at a slight expenditure of the waking state. Like the other psychic formations of its group, the dream offers itself as a compromise serving simultaneously both systems by fulfilling both wishes in so far as they are compatible with each other. A glance at Robert’s “elimination theory,” referred to on page 66, will show that we must agree with this author in his main point, viz. in the determination of the function of the dream, though we differ from him in our hypotheses and in our treatment of the dream process.

The above qualification—in so far as the two wishes are compatible with each other—contains a suggestion that there may be cases in which the function of the dream suffers shipwreck. The dream process is in the first instance admitted as a wish-fulfilment of the unconscious, but if this tentative wish-fulfilment disturbs the foreconscious to such an extent that the latter can no longer maintain its rest, the dream then breaks the compromise and fails to perform the second part of its task. It is then at once broken off, and replaced by complete wakefulness. Here, too, it is not really the fault of the dream, if, while ordinarily the guardian of sleep, it is here compelled to appear as the disturber of sleep, nor should this cause us to entertain any doubts as to its efficacy. This is not the only case in the organism in which an otherwise efficacious arrangement became inefficacious and disturbing as soon as some element is changed in the conditions of its origin; the disturbance then serves at least the new purpose of announcing the change, and calling into play against it the means of adjustment of the organism. In this connection, I naturally bear in mind the case of the anxiety dream, and in order not to have the appearance of trying to exclude this testimony against the theory of wish-fulfilment wherever I encounter it, I will attempt an explanation of the anxiety dream, at least offering some suggestions.

That a psychic process developing anxiety may still be a wish-fulfilment has long ceased to impress us as a contradiction. We may explain this occurrence by the fact that the wish belongs to one system (the Unc.), while by the other system (the Forec.), this wish has been rejected and suppressed. The subjection of the Unc. by the Forec. is not complete even in perfect psychic health; the amount of this suppression shows the degree of our psychic normality. Neurotic symptoms show that there is a conflict between the two systems; the symptoms are the results of a compromise of this conflict, and they temporarily put an end to it. On the one hand, they afford the Unc. an outlet for the discharge of its excitement, and serve it as a sally port, while, on the other hand, they give the Forec. the capability of dominating the Unc. to some extent. It is highly instructive to consider, e.g., the significance of any hysterical phobia or of an agoraphobia. Suppose a neurotic incapable of crossing the street alone, which we would justly call a “symptom.” We attempt to remove this symptom by urging him to the action which he deems himself incapable of. The result will be an attack of anxiety, just as an attack of anxiety in the street has often been the cause of establishing an agoraphobia. We thus learn that the symptom has been constituted in order to guard against the outbreak of the anxiety. The phobia is thrown before the anxiety like a fortress on the frontier.
