Ok, if you are reading this, stay the forget away from my quote bar unless its relevant. When your home alone, try walking through your house with a tape recorder or a camera, just take pictures and record whatever, then post it here so we can creep ourselves out with a real ghost story. Or when noone is around the house, just leave a tape recorder somewhere.
Edit: the guy below me is right, they can do weird things to you if you are possessed, do not provoke anger.
