"A dream commonly has one or more scenes, several characters in addition to the dreamer, and a sequence of actions and interactions usually involving the dreamer. It resembles a motion picture or dramatic production in which the dreamer is a participant-observer. Although a dream is an hallucination, the dreamer experiences it as he does any perceptual phenomenon. Scenes, people, objects, and actions are experienced as though they were impressing themselves on the senses from the external world. The world of dreams, it goes without saying, is a world of pure projection."
Calvin S. Hall
