During hypnosis therapy you are guided into a relaxed state. As you relax, your brain waves slow. Suggestions are able to bypass the ever vigilant amygdala, or gatekeeper, and be delivered to the subconscious and superconscious mind, which are now receptive to new programming.
With slower brain waves comes a heightened state of concentration and focus. You are very aware of the visualizations and suggestions being made. You may feel as though you are more of an observer of thought and images instead of being a part of them.
In this state of deep suggestibility and concentration, the statements bypass the intellectual barriers of the left brain and make their way into the creative right brain. When your brain absorbs what the hypnotherapist says, the words will begin to guide your behavior.
These suggestions, implanted as images and words, help you let go of old negative or limiting patterns, beliefs and feelings, some of which you aren't even aware of. They are replaced with positive and affirming suggestions, creative ideas, and new insights aligned with what you want. It is much like overwriting an outdated computer program with an upgraded version.
