I have told you that, in the first instance, dreams need only be used as sources of material for analysis. At the beginning of an analysis it is not only unnecessary, but also unwise, to make a so-called complete interpretation of a dream; for it is very difficult indeed to make a complete and really exhaustive interpretation. The interpretations of dreams that one sometimes reads in psychoanalytic publications are often one-sided, and not infrequently contestable formulations. I include among these certain one-sided sexual reductions of the Viennese school. In view of the comprehensive many-sidedness of the dream material one must beware, above all, of one-sided formulations. The many-sidedness of the meaning of a dream, not its singleness of meaning, is of the utmost value, especially at the beginning of the psychoanalytic treatment. Thus, for instance, a patient had the following dream not long after her treatment had begun: "_She was in a hotel in a strange city. Suddenly a fire broke out; and her husband and her father, who were with her, helped her in the work of saving others._" The patient was intelligent, extraordinarily sceptical, and absolutely convinced that dream analysis was nonsense. I had difficulty in inducing her to give dream analysis even one trial. Indeed I saw at once that I could not inform my patient of the real content of the dream under these circumstances because her resistances were much too great. I selected the fire, the most conspicuous occurrence of the dream, as the starting point for obtaining her free associations. The patient told me that she had recently read in a newspaper that a certain hotel in Z. had been burnt down; that she remembered the hotel because she had once lived in it. At the hotel she had made the acquaintance of a man, and from this acquaintance a somewhat questionable love affair developed. In connection with this story the fact came out that she had already had quite a number of similar adventures, all of which had a certain frivolous character. This important bit of past history was brought out by the first free association with a dream-part. It would have been impossible in this case to make clear to the patient the very striking meaning of the dream. With her frivolous mental attitude, of which her scepticism was only a special instance, she could have calmly repelled any attempt of this kind. But after the frivolity of her mental attitude was recognised and proved to her, by the material that she herself had furnished, it was possible to analyse the dreams which followed much more thoroughly.
