Unexpectedly we get a hint from a quarter toward which we have not yet looked. Colloquial usage--which after all is not an accidental thing but the remnant of ancient knowledge, though it should not be made use of without caution--our speech, that is to say, recognizes something which curiously enough it calls "day dreaming." Day dreams are phantasies. They are very common phenomena, again observable in the normal as well as in the sick, and access to their study is open to everyone in his own person. The most conspicuous feature about these phantastic productions is that they have received the name "day dreams," for they share neither of the two common elements of dreams. Their name contradicts the relation to the sleeping condition, and as regards the second common element, one does not experience or hallucinate anything, one only imagines it. One knows that it is a phantasy, that one is not seeing but thinking the thing. These day dreams appear in the period before puberty, often as early as the last years of childhood, continue into the years of maturity, are then either given up or retained through life. The content of these phantasies is dominated by very transparent motives. They are scenes and events in which the egoistic, ambitious and power-seeking desires of the individual find satisfaction. With young men the ambition phantasies generally prevail; in women, the erotic, since they have banked their ambition on success in love. But often enough the erotic desire appears in the background with men too; all the heroic deeds and incidents are after all meant only to win the admiration and favor of women. Otherwise these day dreams are very manifold and undergo changing fates. They are either, each in turn, abandoned after a short time and replaced by a new one, or they are retained, spun out into long stories, and adapted to changes in daily circumstances. They move with the time, so to speak, and receive from it a "time mark" which testifies to the influence of the new situation. They are the raw material of poetic production, for out of his day dreams the poet, with certain transformations, disguises and omissions, makes the situations which he puts into his novels, romances and dramas. The hero of the day dreams, however, is always the individual himself, either directly or by means of a transparent identification with another. Perhaps day dreams bear this name because of the similarity of their relation to reality, in order to indicate that their content is as little to be taken for real as that of dreams. Perhaps, however, this identity of names does nevertheless rest on a characteristic of the dream which is still unknown to us, perhaps even one of those characteristics which we are seeking. It is possible, on the other hand, that we are wrong in trying to read a meaning into this similarity of designation. Yet that can only be cleared up later.
