When my friend, who by the way always gets picked on by ghosts, was in her house watching television at about midnight, she saw her jacket fly across the room. Then she smelled this really bad smell, her mother came out and asked what the smell was and she pretty much knew what it was. They say that some ghosts, like an incubus or poltergeist, have this very nasty smell.
Well my friend told her mom it was nothing but cussed the ghost out and told it to go back to my house and leave her alone.
This is weird because while I was reading in bed, I didn't feel the ghost for a while, until one o'clock (remember that it's been caressing my hands each night). I think it actually came back from her house. It had followed her home or something..
