Have you ever been hypnotized to pray during sleep?

A buddy of mine at work says he sees a hypnotist once a month. The hypnotist hypnotizes him so that every time he falls asleep, he prays. He gets in 8 hours of continual prayer every night without even having to think about it. I think I might try it. It sounds like a great idea, but I would defer to the opinion of the experts here before I try it.
