Psychoanalytic literature neglects this subject. Freud believed that colors in dreams are repetitions of those actually seen. Linn contests Dr. Isakower's view that auditory experiences are primary in formation of the superego, pointing out the importance of visual experiences in this function. Moreover it is untrue that expression of the superego in dreams is almost entirely verbal, for color in dreams is also an evidence of function of the superego and, at times, representative of id strivings. It is useful to ask the patient about the shades of colors in a dream and for associations to these colors, which are likely to be numerous.
