It is the emotions which bring us the dream concepts. This is due to the fact that the emotions are far more intimately connected with man’s real being than is the life of thought. We carry them over into sleep. In other words, they are a soul element that remains united with us even during sleep. In contrast with ordinary concepts, the emotions accompany us into sleep; they are far more closely, more intensely, connected with the human individuality than is ordinary thinking, when it is not pervaded by emotion.
