Hypnosis is a natural state of mind that we all experience typically on a daily basis - we just don't call it hypnosis. Whenever you lose track of time deeply immersed in an activity or even find yourself daydreaming, that's a form of hypnosis. We simply bring out and enhance that state on purpose. Nearly everyone on this planet can be hypnotized - the very small percentage that isn't readily "suggestible" commonly still enjoys the relaxation or just experiencing something new. Cynics are often the best people to hypnotize. People do experience hypnosis at different depths, and you don't know until you experience it.
