My screamer

My screamer is a screamer video uploaded to YouTube by a user MagnusThePcNerd on February 24, 2008.

The video starts with a text stating: "Scary. This picture was taken by a man with a disease" then it shows a stock image, then the text appear and it states: "Did you see that??? Something in the background moved, Lets take another look...", However, after a few seconds, an image of Regan MacNeil from The Exorcist with a man screaming appears.
