I know that you are going to think that this is a crazy question...but?

There is no such thing as ghosts that dwell among us. I believe that it is a deception from hell to "fool" people and draw them away from the truth of Jesus Christ. God is not a God of confusion and the whole ghost/spirit/haunted house etc phenominon is a way to confuse people and pull them away from whats real and holy and true into confusion and lies and satanic activity.
