Yes. A girlfriend of mine has some sort of hypnosis certification. It’s not like what you see on TV where someone is going to quack like a duck every time she hears the word X. We all enter hypnotic states throughout the day. Driving down the road and we don’t remember passing the last three exits is a form of hypnosis.
I guess some people are more susceptible than others. My aunt tried hypnosis to quit smoking. Didn’t work. It does help some people though. A lot of people find hypnosis very relaxing. I think being relaxed can be very healing.
Hypnosis, prayer, meditation, I think all are in a similar category. None of it is magic, but it can be very positive and effective for some people.
Then there are those stories of past life regression through hypnosis. The stories are pretty incredible.
