In my psych class my teacher hypnotized all of us. It was quite possibly the most relaxing thing I have ever experience. I would love to do it again. It wasn't hypnotism like you'd think it was, where you become zombie like and would cluck like a chicken if told to (we talked about this and all that is pretty much false). It was more relaxation. It was soothing. And comfortable. Instead if half an hour, I wish it lasted the whole hour and a half of class.
