Let us then proceed with the work on the assumption that the dream is a psychic phenomenon. This makes it an achievement and expression of the dreamer, but one that tells us nothing, one that we do not understand. What do you do when I make a statement you do not understand? You ask for an explanation, do you not? Why may we not do the same thing here, ask the dreamer to give us the meaning of his dream?
If you will remember, we were in this same situation once before. It was when we were investigating errors, a case of a slip of the tongue. Someone said: “Da sind dinge zum vorschwein gekommen,” whereupon we asked — no, luckily, not we, but others, persons in no way associated with psychoanalysis — these persons asked him what he meant by this unintelligible talk. He immediately answered that he had intended to say “Das waren schweinereien,” but that he had suppressed this intention, in favor of the other, more gentle “Da sind dinge zum vorschein gekommen.”23 I explained to you at the time that this inquiry was typical of every psychoanalytical investigation, and now you understand that psychoanalysis follows the technique, as far as possible, of having the subjects themselves discover the solutions of their riddles. The dreamer himself, then, is to tell us the meaning of his dream.
It is common knowledge, however, that this is not such an easy matter with dreams. In the case of slips, our method worked in a number of cases, but we encountered some where the subject did not wish to say anything — in fact, indignantly rejected the answer that we suggested. Instances of the first method are entirely lacking in the case of dreams; the dreamer always says he knows nothing. He cannot deny our interpretation, for we have none. Shall we then give up the attempt? Since he knows nothing and we know nothing and a third person surely knows nothing, it looks as though there were no possibility of discovering anything. If you wish, discontinue the investigation. But if you are of another mind, you can accompany me on the way. For I assure you, it is very possible, in fact, probable, that the dreamer does know what his dream means, but does not know that he knows, and therefore believes he does not know.
You will point out to me that I am again making an assumption, the second in this short discourse, and that I am greatly reducing the credibility of my claim. On the assumption that the dream is a psychic phenomenon, on the further assumption that there are unconscious things in man which he knows without knowing that he knows, etc. — we need only realize clearly the intrinsic improbability of each of these two assumptions, and we shall calmly turn our attention from the conclusions to be derived from such premises.
Yet, ladies and gentlemen, I have not invited you here to delude you or to conceal anything from you. I did, indeed, announce a General Introduction to Psychoanalysis, but I did not intend the title to convey that I was an oracle, who would show you a finished product with all the difficulties carefully concealed, all the gaps filled in and all the doubts glossed over, so that you might peacefully believe you had learned something new. No, precisely because you are beginners, I wanted to show you our science as it is, with all its hills and pitfalls, demands and considerations. For I know that it is the same in all sciences, and must be so in their beginnings particularly. I know, too, that teaching as a rule endeavors to hide these difficulties and these incompletely developed phases from the student. But that will not do in psychoanalysis. I have, as a matter of fact, made two assumptions, one within the other, and he who finds the whole too troublesome and too uncertain or is accustomed to greater security or more elegant derivations, need go no further with us. What I mean is, he should leave psychological problems entirely alone, for it must be apprehended that he will not find the sure and safe way he is prepared to go, traversable. Then, too, it is superfluous for a science that has something to offer to plead for auditors and adherents. Its results must create its atmosphere, and it must then bide its time until these have attracted attention to themselves.
I would warn those of you, however, who care to continue, that my two assumptions are not of equal worth. The first, that the dream is a psychic phenomenon, is the assumption we wish to prove by the results of our work. The other has already been proved in another field, and I take the liberty only of transferring it from that field to our problem.
Where, in what field of observation shall we seek the proof that there is in man a knowledge of which he is not conscious, as we here wish to assume in the case of the dreamer? That would be a remarkable, a surprising fact, one which would change our understanding of the psychic life, and which would have no need to hide itself. To name it would be to destroy it, and yet it pretends to be something real, a contradiction in terms. Nor does it hide itself. It is no result of the fact itself that we are ignorant of its existence and have not troubled sufficiently about it. That is just as little our fault as the fact that all these psychological problems are condemned by persons who have kept away from all observations and experiments which are decisive in this respect.
The proof appeared in the field of hypnotic phenomena. When, in the year 1889, I was a witness to the extraordinarily enlightening demonstrations of Siebault and Bernheim in Nancy, I witnessed also the following experiment: If one placed a man in the somnambulistic state, allowed him to have all manner of hallucinatory experience, and then woke him up, it appeared in the first instance that he knew nothing about what had happened during his hypnotic sleep. Bernheim then directly invited him to relate what had happened to him during the hypnosis. He maintained he was unable to recall anything. But Bernheim insisted, he persisted, he assured him he did know, that he must recall, and, incredible though it may seem, the man wavered, began to rack his memory, recalled in a shadowy way first one of the suggested experiences, then another; the recollection became more and more complete and finally was brought forth without a gap. The fact that he had this knowledge finally, and that he had had no experiences from any other source in the meantime, permits the conclusion that he knew of these recollections in the beginning. They were merely inaccessible, he did not know that he knew them; he believed he did not know them. This is exactly what we suspect in the dreamer.
I trust you are taken by surprise by the establishment of this fact, and that you will ask me why I did not refer to this proof before in the case of the slips, where we credited the man who made a mistake in speech with intentions he knew nothing about and which he denied. “If a person believes he knows nothing concerning experiences, the memory of which, however, he retains,” you might say, “it is no longer so improbable that there are also other psychic experiences within him of whose existence he is ignorant. This argument would have impressed us and advanced us in the understanding of errors.” To be sure, I might then have referred to this but I reserved it for another place, where it was more necessary. Errors have in a measure explained themselves, have, in part, furnished us with the warning that we must assume the existence of psychic processes of which we know nothing, for the sake of the connection of the phenomena. In dreams we are compelled to look to other sources for explanations; and besides, I count on the fact that you will permit the inference I draw from hypnotism more readily in this instance. The condition in which we make mistakes most seem to you to be the normal one. It has no similarity to the hypnotic. On the other hand, there is a clear relationship between the hypnotic state and sleep, which is the essential condition of dreams. Hypnotism is known as artificial sleep; we say to the person whom we hypnotize, “Sleep,” and the suggestions which we throw out are comparable to the dreams of natural sleep. The psychical conditions are in both cases really analogous. In natural sleep we withdraw our attention from the entire outside world; in the hypnotic, on the other hand, from the whole world with the exception of the one person who has hypnotized us, with whom we remain in touch. Furthermore, the so-called nurse’s sleep in which the nurse remains in touch with the child, and can be waked only by him, is a normal counterpart of hypnotism. The transference of one of the conditions of hypnotism to natural sleep does not appear to be such a daring proceeding. The inferential assumption that there is also present in the case of the dreamer a knowledge of his dream, a knowledge which is so inaccessible that he does not believe it himself, does not seem to be made out of whole cloth. Let us note that at this point there appears a third approach to the study of the dream; from the sleep-disturbing stimuli, from the day-dreams, and now in addition, from the suggested dreams of the hypnotic state.
Now we return, perhaps with increased faith, to our problem. Apparently it is very
