I did a little research and found out that the brain operates in 4 different states: Full Conscious Awareness, the Hypnotic State, the Dream State, and the Sleep State. We spend most of our waking hours in the Full Conscious Awareness state, and as we drift into sleep, we pass through the 3 other states. The Hypnotic State is a place where you are not really thinking, you are just experiencing.
When you are hypnotized, the therapist can then make suggestions to your subconscious mind without your conscious mind getting in the way so you can overcome whatever fears or habits you want to get rid of.
When you are hypnotized, you're in an enhanced state of awareness so if you're contemplating going under, don't worry about doing things you aren't comfortable with -- you are actually fully aware of what's going on.
While it did help my friend quit smoking for a short period of time, I'm still a bit skeptical. Have any of you experienced hypnotherapy? Has it worked for you or do you think it's just a big scam?
