14. Knock Knock
You might remember this one. It’s a story of two young siblings left alone in the house. They’re watching TV when they hear a knock at the door. They ignore it just as their parents told them to, but the knocks keep coming. The sister goes downstairs to see who it is, but she doesn’t come back.
The frightened brother sneaks away from the house and knocks on the door of his neighbor’s house. He and the neighbor take a gun and head back to the boy’s house, only to find the sister dead in her bed and a bloody knife on the boy’s bed.
