On being confronted by a ghost, no one seems to want to reach out and try to touch it; neither do the ghosts try to do the same. This brings up the question of how we look to ghosts – is their world as real to them as ours is to us – are the living but shadows in their world? Do they really vanish before our eyes, or do we vanish before theirs?
