We thus see that the day remnants, among which we may now include the indifferent impressions when they participate in the dream formation, not only borrow from the Unc. the motive power at the disposal of the repressed wish, but also offer to the unconscious something indispensable, namely, the attachment necessary to the transference. If we here attempted to penetrate more deeply into the psychic processes, we should first have to throw more light on the play of emotions between the foreconscious and the unconscious, to which, indeed, we are urged by the study of the psychoneuroses, whereas the dream itself offers no assistance in this respect.

Just one further remark about the day remnants. There is no doubt that they are the actual disturbers of sleep, and not the dream, which, on the contrary, strives to guard sleep. But we shall return to this point later.
