My T and I do lots of Hypno. At first I was very leery... But I finally agreed. The thing is I am aware of everything around me. Its mainly used to connect to the sub consious mind and open up blocked events from my past or helping to build of self esteem and help of remove negative thought processes and it does help lower my chronic pain. I always come out of a session feeling really relaxed and happy.
I am a true believer ... I do think your really need to find a provider T that actually knows what he/she is doing. I could in no way address this type of thing to something on YouTube.
Feel free to Pm for more info if you want
