Rh gratification does not take place, and the want continues. In order to equalise the internal with the external sum of energy, the former must be continually maintained, just as actually happens in the hallucinatory psychoses and in the deliriums of hunger which exhaust their psychic capacity in clinging to the object desired. In order to make more appropriate use of the psychic force, it becomes necessary to inhibit the full regression so as to prevent it from extending beyond the image of memory, whence it can select other paths leading ultimately to the establishment of the desired identity from the outer world. This inhibition and consequent deviation from the excitation becomes the task of a second system which dominates the voluntary motility, i.e. through whose activity the expenditure of motility is now devoted to previously recalled purposes. But this entire complicated mental activity which works its way from the memory picture to the establishment of the perception identity from the outer world merely represents a detour which has been forced upon the wish-fulfilment by experience. Thinking is indeed nothing but the equivalent of the hallucinatory wish; and if the dream be called a wish-fulfilment this becomes self-evident, as nothing but a wish can impel our psychic apparatus to activity. The dream, which in fulfilling its wishes follows the short regressive path, thereby preserves for us only an example of the primary form of the psychic apparatus which has been abandoned as inexpedient. What once ruled in the waking state when the psychic life was still young and unfit seems to have been banished into the sleeping state, just as we see again in the nursery the bow and arrow, the discarded primitive weapons of grown-up humanity. The dream is a fragment of the abandoned psychic life of the child. In the psychoses these modes of operation of the psychic apparatus, which are normally suppressed in the waking state, reassert themselves, and then betray their inability to satisfy our wants in the outer world.

The unconscious wish-feelings evidently strive to assert themselves during the day also, and the fact of transference and the psychoses teach us that they endeavour to penetrate
