Nah~ I never heard that. I know only Pervert Ghost from this yaoi.. HA+ http://www.mangago.me/read-manga/dos_obake_ga_nekasetekurenai/
Well you see I don't believe in the existence of ghosts and I am pretty sure the one in my dreams is not a ghost because I couldn't see it , I just felt its hands and fingers but I somehow believe in this term Which means you are possessed by a devil and not a ghost and they say it only shows up when you are asleep in the form of dreams
have you ever heard of sleep paralysis? here's an article about it:

A house I lived in for a little bit was real weird. For some reason every time someone new came over they would end up tripping on the stairs and fallingg into the wall, a few said that it felt like they were pushed. So one night, I was in bed and I felt something sit by my feet, thought it was the cat so I got up and let it out then got back in bed. As I was almost asleep, I felt something sit on the bed, I was scared so I got my teddy bear and buried myself under the covers. That night I had a dream that the TV turned on in the living room play saved by the bell so (in my dream) I got up to turn it off and as I walked by the stairs I felt this massive force just pushed me down the stairs. I woke up drenched in sweat made my way to the living room and turned on the TV and saved by the bell was just starting.
It might seem scary but it was for me. Plus I felt that thing sit. On my bed every night while I lived there
Hmm I'm not sure for me it was my sleep pattern, so I just started working on sleeping when I'm supposed to.
Honestly I'm not sure. I'm not very knowledgeable on sleep disorders so don't take my word for it. But usually with any type of sleep disorder like insomnia, (insomnia can also lead to sleep paralysis in some people.)
The problem is something that's bothering you subconsciously like stress.
Or having an extremely unhealthy sleep pattern.
Though I'm not sure how I got over it. Though it still happens to me sometimes when im sleeping in an unfamiliar place like a hotel, due to be having difficulty falling asleep.
Not manga related but just wanted to share it:p
Have you ever experienced this kind of dream where you are lying in your bed and then suddenly you sense someone's fingers touching your back and neck or the feeling of someone's arms around your waist or someone's hands on your neck trying to strangle you and you feel all of that so vividly like it is reality when it is actually just a dream?? all I could say is that the strangulation one happened 4 years ago and it was so painful and realistic that I thought I was going to die for real!!
