You can. As long as you wish to enter hypnosis, you will. It’s an easy, enjoyable and thoroughly relaxing process.
Everyone goes in and out of trance all day. For example, have you ever driven along a familiar route and not remembered the journey as your mind was elsewhere? Or have you experienced standing in a long queue and your mind has drifted off?
Hypnosis is very like daydreaming, you are not asleep, but in a pleasant altered state of awareness where you are relaxed and focused on your thoughts.
