We have explained that the unconscious impulse which causes the dream connects itself with part of the day’s residues, with some unexhausted interest of waking life; this lends the dream which is thus brought into being a double value for the work of analysis. It is true that, on the one hand, a dream that has been analysed reveals itself as the fulfilment of a repressed wish; but, on the other hand, it will be a continuation of some preconscious activity of the day before and will contain subject-matter of some kind or other, giving expression, for instance, to a determination, a warning, a reflection or once more to the fulfilment of a wish. Analysis exploits the dream in both directions as a means of obtaining knowledge alike of the patient’s conscious and of his unconscious processes. It also profits from the fact that dreams have access to the forgotten material of childhood, and so it happens that infantile amnesia is for the most part overcome in connection with the interpretation of dreams. In this respect dreams achieve a part of what was previously the task of hypnosis. On the other hand, I have never maintained the assertion which has so often been ascribed to me, that dream-interpretation shows that all dreams have a sexual content or are derived from sexual motive forces. It is easy to see that hunger, thirst, or the need to excrete, can produce dreams of satisfaction just as well as any repressed sexual or egoistic impulse. The case of young children affords us a convenient test of the validity of our theory of dreams. In them the various psychical systems are not yet sharply divided and the repressions have not yet grown deep, so that we often come upon dreams which are nothing more than undisguised fulfilments of impulses left over from waking life. Under the influence of imperative needs, adults may also produce dreams of this infantile type.
