I have lived among ghosts, this much I know. Me and Steve lived in a house that was haunted by its last inhabitants, it seems. "Goldy", a man, and possibly his wife. They were downright poltergeists, making sounds like ghosts in the movies --- woooo-- and just generally fooling around. After being lost , my Bic lighters and Chapsticks would just fall from the middle of the room, suddenly there. There would be the sound of large nails (like a bear) scratching wood throughout the night.
We didn't stay in that place very long. Did a seance with the woman who lived in the first floor shortly before we all moved out.
Tried to convince the restless spirits to move on. Certainly we were.
