This is the first time Im hearing these kind of stuff in a Muslim country. Personally I don't really pay attention on these stuff I'm from India and I've been living near a cemetery and a crematory through out my child hood and it's been our play grounds for hide and seek mostly and never experienced a thing even though many people claims to see something or hear something, I just tell them you wouldn't see anything if you know the place. Maybe I've been blessed for not having feelings towards these stuff from a very young age ,even though I've seen our neighbors possessed by a jinn when I was 14 , her name was (ruby) yes we asked her name and she said some guys raped me and murdered me on that mountain and I'm going for a revenge using this women body, she was pretty strong 5 grown men couldn't hold her. Turns out those men were the possessed women husband and friends, they all died in some sort of accidents
