Would certainly be an interesting lead on the discussion of God's existence.
Come to think of it, I asked the guy if he asked the ghosts about Jesus, he said he did. I don't remember the answer they gave exactly (as he related it) but it was some cryptic connection from the bible I think.
Havn't seen the guy since -shrugs-.
One thing stuck in my memory, the guy asked the ghosts why they were still there. They said "they won't let us leave".
He also asked who the ghosts were, one answered and when he went back the next day, he found the tombstone of the ghost that had responded to him.
