Actually, you probably need to see it for yourself to believe it. Reading it won't make you believe.

But be aware that there are spiritual realms out there. I saw a possessed man once who spoke in an ancient Javanese language that only a few people know. He worked as a nanny to my parents and I told him to jump over a certain very sacred area. Guess what, the demon is scared of the cross and prayer offered up by a young teenager girl (my sister).
