From a segment of a patient's analysis the author deduces some theories on the metapsychology of color in dreams. Color in dreams partakes of the resistance and regression inherent in the sensory image of a dream. Color, usually removed by the repressing forces of censorship, may appear when there is danger of a return of the repressed; it represents further regression. Scoptophilic and exhibitionistic impulses form the basis of the latent content of color in dreams; the surprise, fascination, and mystification with which the patient reacts when color in a dream is brought to his attention is directly connected with scoptophilic impulses. Many color dreams are concerned with the primal scene. Perception of color and exploratory impulses probably develop at the same time in the child. Certain problems of color in dreams demand investigation.
