Listen to this song until u forget about it:
link ...Oh seconde thought, the cartoon guy is slightly creepy...
Well, u just have to find something really annoying and funny, you'll eventually forget about it. If its night, try to keep light around u at all times. Also, try to stay away from mirrors (they creep me out).
Actually, u should listen to a funny song while doing some other thing, so you'll get addicted to this song, and be busy focusing on some sort of work. If a family member of friend is close by, u could stick door them and talk about something interesting.
