Can anyone be hypnotised?

Generally yes, but only if you co-operate and allow yourself to be. The trance state is like daydreaming and a very natural state which we all experience daily.

Will I be aware of what is happening?

Yes, and you will be totally in control.

Won’t I be asleep?

No. You will be very relaxed. You may find at times that your mind wanders, a little like daydreaming.

What dangers are there?

None, with a good therapist.

Are there any side effects?

Yes, beneficial ones.

Supposing I don’t wake up?

This is impossible. The most which could happen is that you would drift into a normal relaxed sleep and awaken when you were ready.
