the human mind could be playing tricks. you might be scared to sleep, cause yu think ull wake up dead. even if you dont realize that fear is in you.all this shows is that the human mind is complex on a number of levels....and its a total bitch when your scared :D
youre just scared.I played sonic r and tagged super sonic with tails doll and couldnt go to sleep because i was scared. No worries anymore because that didnt summon him:)
