A man was taking pictures of himself using the self-timer on the polaroid camera.
After taking a few pictures he noticed a shadow in the corner of one picture.
He turned around but there was no one behind him. There was only himself in the room.
He took one more picture and in it he saw a strange man standing behind him. But when he turned around there was no one there, as before.
He then took yet another shot and this time the picture showed the same stranger raising a knife high in the air, ready to strike him...
He stopped taking pictures immediately but who knows what would have happenned if he had shot sequence photographs..?
