Eh. Yes and No.
My friend used to live in a house that was converted from a Civil War hospital into a house. They believed in ghosts, walking up and down the stairs and shit, all that stuff. I always just took it as bad stairs and such.
Though one day after a party, being the only person that stayed sober, I helped him clean up, cleaned out a bunch of stuff in his bomb shelter... he asked me to close the door, and the thing slammed shut HARD. Definitly wasn't the wind, becuase well this was a heavy ass door, and there wasn't any wind anyway being underground.
Was just in the shelter and cleaned everything up so I know nobody was in there or any shit like that.
Don't really have an explination for it other then ghosts, though I don't see why a "ghost" would be trapped on earth.
