A method is presented for the study of dreams and other unconscious processes by hypnosis. In hypnosis certain subjects have more awareness of the meaning of dream language than in the waking state. This awareness is influenced by the relationship between hypnotist and subject. The similarity of this relationship with other interpersonal relationships was pointed out, as well as the possibility of using this method for the study of transference. A number of experimental dreams, evoked by both sexual and nonsexual dream stimuli, are presented and their special characteristics discussed. The results obtained illustrate the great plasticity of the dream language and argue against too narrow interpretation of symbols.
