Anyone experience the Choking Ghost? Heres a scientific explanation of such horror.
An article I came across.... "Demonic presences looming over a sleeping person, or even leaning on their chest or choking them have been part of ghostly lore for centuries. Modern science, though, has come up with evidence that points toward a completely natural explanation that offers some crumb of comfort to those paralysed people lying in bed waiting for the demonic presence to come and kill them in some horrible way. It's called sleep paralysis, and it is an accidental side effect of a generally helpful characteristic of the sleeping body. Normally, the body switches off movement when it sleeps, to prevent problems like sleepwalking, and when a person wakes up, this paralysis turns off. Those threatening faceless presences next to the bed are artifacts created by the brain in sleep mode, and the person only sees and remembers them when he wakes up but is still stuck in paralysis mode, so he cannot move or scream.
