is that the work of interpretation is not directed to the entirety of the dream, but to each portion of the dream content by itself, as though the dream were a conglomeration, in which each fragment demands a particular disposal. Incoherent and confused dreams are certainly the ones responsible for the invention of the cipher method.[S] The worthlessness of both these popular interpretation procedures for the scientific treatment of the subject cannot be questioned for a moment. The symbolic method is limited in its application and is capable of no general demonstration. In the cipher method everything depends upon whether the key, the dream book, is reliable, and for that all guarantees are lacking. One might be tempted to grant the contention of the philosophers and psychiatrists and to dismiss the problem of dream interpretation as a fanciful one. I have come, however, to think differently. I have been forced to admit that here once more we have one of those not infrequent cases where an ancient and stubbornly retained popular belief seems to have come nearer to the truth of the matter than the judgment of the science which prevails to-day. I must insist that the dream actually has significance, and that a scientific procedure in dream interpretation is possible. I have come upon the knowledge of this procedure in the following manner:— For several years I have been occupied with the solution of certain psychopathological structures in hysterical phobias, compulsive ideas, and the like, for therapeutic purposes. I have been so occupied since becoming familiar with an important report of Joseph Breuer to the effect that in those structures, regarded as morbid symptoms, solution and treatment go hand in hand.[T] Where it has been possible to trace such a pathological idea back to the elements in the psychic life of the patient to which it owes its origin, this idea has crumbled away, and the patient has been relieved of it. In view of the failure of our other therapeutic efforts, and in the face of the mysteriousness of these conditions, it seems to me tempting, in spite of all difficulties, to press forward on the path taken by Breuer until the subject has been fully understood. We shall have elsewhere to make a detailed report upon the form which the technique of this procedure has finally assumed, and the results of the efforts which have been made. In the course of these psychoanalytical studies, I happened upon dream interpretation. My patients, after I had obliged them to inform me of all the ideas and thoughts which came to them in connection with the given theme, related their dreams, and thus taught me that a dream may be linked into the psychic concatenation which must be followed backwards into the memory from the pathological idea as a starting-point. The next step was to treat the dream as a symptom, and to apply to it the method of interpretation which had been worked out for such symptoms.
