It is an outdated term. It is a state of altered consciousness; the individual is fully alert, more alert than you actually are at this very minute. We all go in and out ‘of trance’ throughout our days. You may recall a time when you were reading a book and as you were deeply absorbed in the story, you did not hear another person attempting to get your attention. In actuality, you did hear this person, but because you were so engrossed in your story – you were ‘in trance’ therefore, you were oblivious to the person speaking to you.
In hypnosis, you are far more alert than you are right now. I educate my clients to understand, while in hypnosis, for any reason they decided to come from that natural altered state, they would immediately emerge.
