The short answer is yes. Trance is a natural we fall into several times a day.
When was the last time you've been in a hypnotic trance? When you first woke up this morning , when you drift off while reading or watching the TV . Just before you fall asleep.
These are all trance states. We even drive to work in trance, if you are driving the same way every day. You get the idea.
Sometimes we go deep, sometimes gentle.
The myth that only some people can be hypnotised comes from watching stage hypnosis.
Stage shows seen on TV where someone is brought into the deepest level, and then performs some comedy act that their not aware of.
In this context only some people can be hypnotised this deep and be manipulated to think they are a chicken. This is called somnambulism .
But for clinical hypnosis, it isn't necessary to go this deep. In fact often isn't helpful.
People come to a hypnotherapist to gain more control not to lose control. Sometimes trance can be called focused attention.
In trance you are more in touch with your subconscious, This is where all your life experiences are. Good and bad. Hypnosis is a great way to get you in touch with the control room of your mind and body .Its a bit like trying to recall the name of that actor that was in that movie. You cant quite remember. but you know its in there. Beliefs and programmes act in a similar way. Asserting influence over us ,just under our awareness.
Hypnosis can be a great way to access the power within.
