Hypnosis is nothing more than a relaxed state of focused attention, similar to daydreaming.
Because hypnosis is the direct route to the subconscious mind, it is one of the easiest and most effective ways to change counterproductive beliefs and behavior. Contrary to popular opinion, the hypnotist doesn't control you, and you can't be made to do anything against your morals, ethics, or beliefs under hypnosis. You're in full control at all times in hypnosis.
