A previous study of the effects of hearing one's own voice during sleep was replicated, and the results supported those of the previous experiment. Hearing one's own voice during sleep produces dreams in which the dreamer is active, assertive and independent. Hearing another person's voice during sleep produces dreams in which the dreamer is passive. There was a high degree of voice recognition during the dream as compared with a somewhat lower rate of recognition during the waking state. Free associations following the rapid eye movement period awakening seemed congruent with dream content.
