Serafin;
The things you describe sound more like toxins in the body coming out. We have so many chemicals in our diet and medications these days that don't mix well in the body. Any kind of exercise can stir things up and give you a nasty experience.
Perhaps you could consider this. There are detox programs that might serve you far better before doing something like Holosync.
Or also consider looking at allergies. I'm not disagreeing with you although there may be other circumstances that help create what you have experienced.
Everyone knows that Asbestos is bad for you although if you don't smoke it doesn't seem to have much effect on non-smokers. When the two are combined the statisics for lung disease start climbing through the roof.
