Sex Dreams, Wet Dreams, and Nocturnal Emissions

This study provides an overview of the frequencies and narrative features of sex and wet dreams and investigates the incestuous behavior in the manifest content of dreams. A questionnaire specially designed for capturing both quantitative and qualitative aspects of sex and wet dreams was administered to 58 male participants. More than 80% of participants had dreamed about having vaginal intercourse with a woman. Dreaming of sexual interactions other than vaginal intercourse—such as oral sex—was also common. Consistent with the hypothesis that latent sexual motives or some variation of sexuality that people may not be aware of during the daytime would emerge at night through dreaming, both homosexual and incestuous behaviors were observed in dreams. In addition, the finding indicates that sexual thoughts and motives can be represented by symbols in dreams, and dream impressions involving no erotic scenes are capable of eliciting nocturnal emissions. It seems that sex dreams, wet dreams, and nocturnal emissions without erotic imagery or dreaming can be distinguished from each other.
