I started reading clinical psychology books at age 15, literally a book a month. I majored in psychology in college earning my degree. And I've read hundreds of psychology books since college. Hypnotherapy was just the next step up.
I'm a "direct medical hypnotist" in that I help people with severe issues that would normally require doctor or hospital visits. Direct means using "commands" instead of "suggestions."
In my first 7 years, I worked with 3 actual medical doctors who incorporated "direct / command" hypnosis techniques for burn patients, cancer patients, PTSD patients and those in extreme physical or emotional pain.
I'm also an "indirect clinical hypnotist" where I also use metaphors and story telling techniques which were created by Milton Erickson which are good techniques for simple and superficial issues like nervous habits and phobias. Indirect means using "suggestions" instead of "commands."
And I'm a "corporate stage hypnotist" because of my knowledge in Medicine and Stress Management techniques.
I continued to expand my knowledge of the power of the mind by spending years studying, practicing and helping others using the following:
√ Cognitive Behavioral Therapy
√ Visualization Techniques
√ Progressive Relaxation
√ Autogenic Training
√ Stress Management
√ Pain Free Childbirth
As for "comedy" stage hypnosis for schools and parties, anyone with half a brain and a very limited knowledge of hypnosis can entertain people. It takes very little knowledge of hypnosis to say "relax this muscle, that muscle, sleep, now dance like a drunken monkey."
