Hypnosis is a completely natural state of the mind, if you are open and committed to working with the therapist anyone (except the mentally impaired) can easily move into this state of heightened relaxation.
If you want to make changes through hypnotherapy, you can be hypnotised. People who don’t want to be hypnotised, don’t let themselves be.
You may be a perfect subject for Hypnosis and not be ready to change. Or you could be the worst subject with a strong desire to change. You will only know when you try.
