When I was about five or six my friend's older sister told me there was an evil spirit of a girl who had gotten hit by a car that lived on her car's roof. Only the girls spirit was SO evil that she eventually turned into a monster that ate people's heads when they got out of the car she was on.
--at this point she hit the top of the car when I wasn't looking and then told me the girl had just hopped on her car.
It took her mom and mine thirty minutes to get me out of the back of the van because I was so hysterical and simply would not get my head cut off.
