Twenty-six deaf college students were interviewed in the language of signs and manual alphabet to obtain information concerning the symbolic and perceptual processes experienced in their dreams. It was found that the dreams of the congenitally deaf were vivid, brilliantly colored, and reported as frequent in occurrence. Usually the language of signs was the means of communication in the dream, but in dreams in which affect was prominent, primitive signs were often utilized. The characteristic differences in the dreams of the deaf were most marked in the congenitally deaf, less marked in those with acquired deafness before age 5, and least marked in those with acquired deafness after age 5.The relevance of these findings to superego formation, non-verbal communication processes, and recent observations in experimental sensory deprivation is discussed.Abstract Teaser
