The dream is specifically the utterance of the unconscious. We may call consciousness the daylight realm of the human psyche, and contrast it with the nocturnal realm of unconscious psychic activity which we apprehend as dreamlike fantasy. It is certain that consciousness consists not only of wishes and fears, but of vastly more than these, and it is highly probable that the unconscious psyche contains a wealth of contents and living forms equal to or even greater than does consciousness, which is characterized by concentration, limitation and exclusion.
