- I am a traditional Catholic, and I can say that for us, such stories are not mere fairy tales. The spiritual world is something entirely normal for a Catholic. We are convinced that demonic possessions do happen (at the invitation of the person themselves), although many cases are simply mental illnesses. Traditional Catholics, however, should not be particularly interested in this, let alone listen to any messages from the devil. One does not negotiate with the devil :-)
