it can stop you from breathing in your sleep, its like a ghost its some evil omen you can wake up feeling raped up the ass even when I was a virgin and the door would open nothing is there, doors slam no one there. I literaly sat out on the veranda one day til my mum came home I was so terrified. and I know I sound crazy, so I don't talk about it. https://www.youtube.com/watch?v=QmbpOucNVn4
