I am a beginning hypnotist, and know a good bit about it. Basically, you don’t get knocked unconcious, nessicarily. Hypnotism is basically using words to relax a person to a state where they close their consious mind, and allow the hypnotist to speak directly to the subconsious. Since your subconsious can only process one thing at a time, you can’t access your contradictory knowledge. If the hypnotist tells the person they are a racecar driver, they don’t know they aren’t. So basically, hypnosis is just an altered state, you don’t neccisarily black out. It just feels really relaxing, and although a bit of amnesia is normal, its not garentueed.

sorry about my spelling.
