Dream, Wish-Fulfillment, Psyche

Implicit in Freud's concept of a dream as wish-fulfillment are the main constituents of his concept of the Psyche--the Id as the source of the wish, the Superego as the source of the taboo of real fulfillment of the wish, and the Ego as the source of the diversion of the wish to a harmless fulfillment.  In turn, from those components, he develops a theory of society, including concepts of civilization, religion, and history.  However, many dreams are merely vague products of a reflux of images from the day's events, in combination with routine physical sleeptime motions.  Accordingly, the generalization of the concept of dream as wish-fulfillment is inadequate, as is, therefore, the system founded on it.
