Stages of Consciousness
Hypnotherapy practices deal with four stages of consciousness: Beta, Alpha, Theta, and Delta.
Normal waking consciousness is called Beta. In Beta, a person's brain is fully functional and in an alert state. It is paying attention to, and processing stimuli from the outside world.
In Alpha, the person is slowed down slightly and is therefore more focused and able to dedicate her train of thought to one thing. Equate Alpha to the state you are in when watching TV, or when you have been driving for a lengthy period. When driving, your attention is focused on the elements of driving. Outside stimuli play a lesser role. At first, you may be aware of things around you such as cars and pedestrians. After prolonged driving, your attention shifts to what is happening directly in front of you. This is Alpha.
Alpha is a "not-really-here, not-really-out-of-it" phase. In Alpha, outside stimuli no longer distract the client, who is then able to receive habit-altering messages from the hypnotherapist.
It is important to note that similar to driving in a trance, patients in hypnosis still can react as things happen. A common misconception is that clients under hypnosis cannot react, and that therefore the hypnotherapist has ultimate control over the patient. In Alpha, the patient is always in the driver's seat, and is fully capable of reacting and making decisions.
