Will I Be Totally Unconscious?

NO! You are always aware of where you are and what is happening! This is a misconception resulting from hypnosis "shows". There is no such thing as being "Under hypnosis"! Remember that hypnosis is just daydreaming and daydreaming isn't scary, and actually doesn't feel all that unusual. 

During hypnosis you are actually more alert than when awake but most of your attention is focused inwards. You are in a deeply relaxed state where your conscious mind relaxes, allowing your unconscious mind to listen and to react. You know that I'm talking to you. You know why you're here. You don't need me to tell you what happened or what you said.

Often you can remember past events more clearly and can also visualise things better, and in more detail.

Many people, especially in their first session, can be a bit apprehensive, and so may resist a little. They often believe that because they remember every word, and also remember "thinking" during the session. that this means that they have been hypnotised. This is perfectly normal. You are able to remember everything that you want to remember.

Once you discover that nothing unpleasant, or untoward, is going to happen to you, you will learn to relax more deeply, and will probably find yourself daydreaming for much of the session. This is fine, too! Therapy is very effective no matter how active your mind is.

As I have said elsewhere, I don't like stage hypnotism. However, it wouldn't be much of a show if the "victims" couldn't respond, or were unresponsive!
