Don't look in to the keyhole
(one of my friend's telling)
A man's car broke down, so he went to the nearest motel. He took a room and everything was okay. But he heard voices of the nearest room and was curious who lived there. So he went out of his room and peeked inside in the room of the keyhole. He saw a woman, doing the usual thing. The man went back to this room and went to bed.
The next night happened the same thing; the man was curious what happened in the other room. This time, when he looked in the keyhole, he saw nothing but red. The man didn't know what it was and he was curious who was there, so he asked the motel's keepers about the room. He said that a couple years ago there had lived a family. And the huspand had killed their two kids and the wife, who's eye had been red.
