It's tempting to lay hypnotic trance off to a sleep state. Many first timers think I'm going to knock them out and fiddle with their brain. That is not the case. Hypnotic trance is not sleep. In fact while you are in trance your brain will be completely aware, just as you are when you watch a movie or TV. Incidentally, both of those media are capable of putting you into a light hypnotic trance. That is why advertising LOVES them!
In hypnotic trance your brain will be futzing along, questioning, doubting, day dreaming, getting distracted, plotting what it's going to do when the session ends, in other words, doing all the things it normally does. One embarrassing fact revealed in hypnotherapy is that much of what we call "thinking" is just habit, more like a rehearsal or recital. Or a dream. After all your brain is working while you are sleeping.
Throughout the session, you'll think you are quite alert, right up to the point you hear me say, "1-2-3-4-5, eyes open, wide awake." At that point you'll be surprised, that you feel a little (or a lot) groggy and that your eyes open a little reluctantly!
In deep trance states you may feel a little "muffy," somewhat detached. You may experience time distortion, 20 minutes may seem like 10 or the other way around. You may feel odd sensations in your arms or hands, numbness or tingling. You may not remember portions of the session—though you'll remember being wide awake.
No matter what, you will always be in control. After a session the effects may be immediate or delayed but almost always something positive happens. You'll not want that cigarette, you'll find you are able to eat normally, or the pain has subsided. What ever it is, your issue will respond.
Like any kind of learning, hypnosis is cumulative. While some clients are surprised by an immediate change, usually the first effects may wear off after a few days. After all, your habits took a while to become hard-wired so, expect that re-wiring them may take a series of sessions. However long it takes, it'll be half the time of traditional therapy, and half the price.
