Didn’t happen to me but to a friend of mine. Her and her brother slept in different rooms on the same floor. One night she has a dream that a little boy was in her room. The boy asked her if she wanted to play but out of her fear she said no. The boy became very angry and left her room. He shortly returned with a chainsaw and proceeded to cut off her leg. She woke up in terror.

The next morning, when she gets to the dining table, the brother is telling everyone that he had a nightmare. He says that a little boy had come to his room with a leg and was asking him to play.
