Paranormal encounters aren’t unusual, but having sexual experiences with ghosts? That’s a bit out there. It actually has a quasi-scientific explanation. In the world of dream research, an incubus encounter is an experience where you’re awakened while sleeping, but have hallucination-like visions. Sometimes these encounters fall a little to the X-rated side of the spectrum. It can be terrifying, or, as these celebrities have found…enjoyable? These stars are fine with sharing their sexual ghost encounters with the public.
