So what actually is hypnosis and what does it feel like?  

Most people have a natural curiosity about what hypnosis is actually like. Some worry it may be dangerous or embarrassing...that somehow their personality will be changed afterwards or they may act in an inappropriate way. Other people fear they may say something they regret under hypnosis, revealing secrets they don't want to share. And often people think they 'can't be hypnotised' and it 'won't work for me.'
