It’s possible you weren't Hypnotised.
The solution to this is to know exactly what to expect before going into hypnosis. All good clinical hypnotherapists will conduct a thorough preliminary consultation with all new clients. This is a very important session that will explain what hypnosis is, how it works and what to expect before you attempt hypnosis. If you neglect this session you will have to learn what hypnosis is and how to do it through trial and error which is time consuming and expensive. Always check that your hypnotherapist conducts a thorough preliminary consultation with you. I consider the preliminary consultation to be the most important session and it should most definitely not be a ten minute meeting to acquaint yourself with the person you’ll be working with.
