Somnophilia (from Latin 'somnus' = sleep an Greek φιλία, '-philia' = love), or sleeping princess syndrome or Sleeping Beauty syndrome, is a paraphilia in which sexual arousal and/or orgasm are stimulated by intruding on and awakening a sleeping stranger with erotic caresses, but not with force or violence. The eye-rolling before fainting may also cause arousal. Somnophilia may also refer to having sex with a sleeping partner or rubbing against the body with the private parts or hands. There is no literal term for the reciprocal paraphilic condition of being the recipient, which more often occurs in fantasy than in reality.
