Rh amount of excitement. The mortification brought on thirty years ago, after having gained access to the unconscious affective source, operates during all these thirty years like a recent one. Whenever its memory is touched, it is revived and shows itself to be supplied with the excitement which is discharged in a motor attack. It is just here that the office of psychotherapy begins, its task being to bring about adjustment and forgetfulness for the unconscious processes. Indeed, the fading of memories and the flagging of affects, which we are apt to take as self-evident and to explain as a primary influence of time on the psychic memories, are in reality secondary changes brought about by painstaking work. It is the foreconscious that accomplishes this work; and the only course to be pursued by psychotherapy is to subjugate the Unc. to the domination of the Forec.

There are, therefore, two exits for the individual unconscious emotional process. It is either left to itself, in which case it ultimately breaks through somewhere and secures for once a discharge for its excitation into motility; or it succumbs to the influence of the foreconscious, and its excitation becomes confined through this influence instead of being discharged. It is the latter process that occurs in the dream. Owing to the fact that it is directed by the conscious excitement, the energy from the Forec, which confronts the dream when grown to perception, restricts the unconscious excitement of the dream and renders it harmless as a disturbing factor. When the dreamer wakes up for a moment, he has actually chased away the fly that has threatened to disturb his sleep. We can now understand that it is really more expedient and economical to give full sway to the unconscious wish, and clear its way to regression so that it may form a dream, and then restrict and adjust this dream by means of a small expenditure of foreconscious labour, than to curb the unconscious throughout the entire period of sleep. We should, indeed, expect that the dream, even if it was not originally an expedient process, would have acquired some function in the play of forces of the psychic life. We now see what this function is. The dream has taken it upon itself to bring the liberated excitement of the Unc. back under the domination of the foreconscious; it thus affords relief for the excitement of the Unc. and acts as a
