The Church does not condemn reading or studying supernatural phenomena, nor has she denied the fact that such occurances can or do exist. As the Church believes there is more to our existence than what can be seen, it is not incompatible with the faith to believe in ghosts, as it is entirely possible that these are departed souls, angels or demons.
That having been said, the Church expressly and vigorously condems the attempt to communicate with such phenomena of our own accord. Superstition, seances, witchcraft, etc are, as the Catechism states, an attempt by man to gain power which is rightly reserved to God alone. Study of this “bell witch” ghost is one thing. However, there exists the temptation with such study to attempt to experience these things for oneself, which is a very dangerous proposition.
