Why does this man keep coming back every night?

Well, this all started happening a few nights ago. I was dreaming about unicorns in leotards like usual when I woke up and saw this creepy guy standing over my bed. He started talking to me about his abnormal body hair and then he left. I decided not to tell anyone since no one would believe me. The next night he was sitting on me and farting a christmas carol. When I screamed he shoved a blanket in my mouth and jumped out my window. I should stop leaving my windows open... The third night he came back and told me his name was Afro Thunder Tattoo Wonder and he wanted to shimme with me. I got my lamp and tried to hit him but he punched me in the face and leaped back out the window. I don't want him to come back tonight so I'm going to sleep outside. Do I have problems? How do I get rid of him? Oh and he added me on facebook and this is how he looks: http://i.crackedcdn.com/phpimages/members/avatars/3/4/4863_170.jpg?1
