This is a story I heard from a friend of mine, it happened to a coworker of his. She Moved into an apartment a few months back with her son, who's about 3 years old. After a few weeks the boy started coming into her room in the middle of the night, complaing about a monster that was scaring him. When she asked him about the monster, he told her that it was black/shadowy with red eyes, and it called itself Sunny. Sunny would tug at him and pull his sheets off. She would let him sleep with her, but he kept coming to her in the middle of the night saying Sunny was scaring him. She started to do some research and asked the land lord, and apparently, a man had killed himself in her sons room, years ago, and his name was Sunny. She didn't know what to do so she let him sleep with her until she could find a new place to live. Then, a few weeks ago, she updated my friend on a new occurance. They were in her room, she was doing while her son Played with his toys. Suddenly he started complaining that Sunny was scaring him. She asked him where he was and he pointed to the doorway. She looked and didn't see anything, but he kept pointing and asking her if she could see him.
Edit: okay, now I'm finished.
