Abstract

Somnophilia refers to the interest in having sex with a sleeping person. Using an online sample of 437 participants, the present study provides the first empirical examination of somnophilia, its various forms, and theorized correlates. Participants completed the newly developed Somnophilia Interest and Proclivity Scale, which comprises three subscales (Active consensual, Passive consensual, and Active non-consensual somnophilia). In order to test hypotheses about the convergent and divergent validity of different paraphilic interests, participants also completed scales measuring necrophilic, rape-related, and sadistic/masochistic sexual fantasies, rape proclivity, and the need for sexual dominance/submission. Male participants scored higher than females on all scales except the passive subscale. For both males and females, each subscale was associated most strongly with conceptually-congruent variables. These results support existing theoretical assumptions about somnophilia, as well as offering newer insights, such as distinguishing between active and passive somnophilia. Limitations and implications for further research are discussed.
