If you're looking for a scary ghost video, you might like this one.
"Mother? What's wrong with me?" Exorcist (1973)
Its creator attests to its authenticity.
Imagine looking in the mirror or standing in front of a window at night. You are all alone in the house and you are peering out the window trying to see outside into the darkness. However, the light in the room behind you causes your reflection to be cast upon the glass.
Over your shoulder, just slightly above you, you notice the reflection of something you know is not supposed to be there. It's the reflection of a face floating right behind you!
Your heart stops, you spin around and nothing is there. Turning around once more, the face reappears, but this time its features become more and more clear. A chill runs down your spine, you scream and run through the house turning on all the lights.
If it sounds as though you would react that way in the same situation, you might enjoy it. See if you think this is really ghost video footage.
