right as the day dream. The present is the tense in which the wish is represented as fulfilled.
The second quality, however, is peculiar to the dream as distinguished from the day dream, namely, that the presentation content is not thought, but changed into perceptible images to which we give credence and which we believe we experience. Let us add, however, that not all dreams show this transformation of presentation into perceptible images. There are dreams which consist solely of thoughts to which we cannot, however, on that account deny the substantiality of dreams. My dream "Autodidasker—the waking phantasy with Professor N."—is of that nature; it contains hardly more perceptible elements than if I had thought its content during the day. Moreover, every long dream contains elements which have not experienced the transformation into the perceptible, and which are simply thought or known as we are wont to think or know in our waking state. We may also recall here that such transformation of ideas into perceptible images does not occur in dreams only but also in hallucinations and visions which perhaps appear spontaneously in health or as symptoms in the psychoneuroses. In brief, the relation which we are investigating here is in no way an exclusive one; the fact remains, however, that where this character of the dream occurs, it appears to us as the most noteworthy, so that we cannot think of it apart from the dream life. Its explanation, however, requires a very detailed discussion.
Among all the observations on the theory of dreams to be found in authorities on the subject, I should like to lay stress upon one as being worth mentioning. The great G. T. Fechner35 expresses his belief (Psychophysik, Part II., p. 520), in connection with some discussion devoted to the dream, that the seat of the dream is elsewhere than in the waking ideation. No other theory enables us to conceive the special qualities of the dream life.
The idea which is placed at our disposal is one of psychic locality. We shall entirely ignore the fact that the psychic apparatus with which we are here dealing is also familiar to us as an anatomical specimen, and we shall carefully avoid the temptation to determine the psychic locality
