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 like 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.[1] It may therefore seem that the conscious wish alone has been realized 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.
