Are ghosts real or fake?
We really do not know. To the best of my knowledge the Catholic Church has no official position on ghosts. The doctrine of heaven and hell would seem to negate any reason for ghosts to be the souls of dead people. However paranormal phenomena seems to exist. These phenomena may come from sources other than the souls of people in heaven, hell, or purgatory. We simply do not know. The Church is very suspicious of people who claim to talk to ghosts. With love in Christ.
