Spectrophilia
The term "spectrophilia" describes both the phenomena when people think they've had sexual contact with a ghost and the fetish of thinking about having sex with ghosts or spirits. Another definition of it is the sexual attraction to examining oneself or other people in a mirror.
Dr. Anil Aggrawal's "Forensic and Medico-Legal Aspects of Sexual Crimes and Unusual Sexual Practices" is the only scholarly work that is known to refer to spectrophilia. Arousal at seeing oneself in the mirror, coitus with spirits, or sexual attraction to ghosts are other definitions of it.
Spectrophilia have been reported throughout history. Scientists have linked them to a condition known as sleep paralysis, which 20% of people claim to have experienced. Those who have had a "sleep demon" experience say they feel like a spirit is sitting on top of them or having sex with them. Between the lighter and deeper (REM) stages of sleep, a person may have a sleep-related hallucination, which is thought to be the cause. The person feels awake and cognizant even if their body is still paralyzed (as in REM sleep) because they are in between stages of sleep.
More About Spectrophilia
Two kinds of ghosts are said to visit the living in folklore: the succubus, a female spirit attempting to conceive by a human man, and the incubus, a male spirit that tries to impregnate a woman with ghost sperm. Accounts and information about gay spectrophilia are pretty scarce.
Of course, there are many things that individuals can and do dream about. According to internet sources, the great majority of persons who identify as electrophiles have fantasized about having sex with a ghost but have never actually done so. Nevertheless, there is no proof that a ghost has ever impregnated a person, and there is also a dearth of empirical data regarding human coupling with the spirit realm.
