Demonic Possession on the Rise?

The Telegraph reported on January 5, 2014, that according to the Catholic Church, demonic possession and exorcisms are on the rise. They say this is a result of more people dabbling in black magic, paganism, Satanic rites, Ouija boards, and even yoga. Is this true? What does the Bible say about the practice of casting out demons? Could it be that an apparent “exorcism” is nothing else but a demonic deception?
