Is it dangerous ? Will I completely lose control on myself ?

The answer is no ! Even if you come across a very ill-intentioned hypnotist (which is not my case!) and he decides to make you imitate the chicken or to feel you in space in a state of weightlessness, he would not succeed if you do not agree: your subconscious mind protects you, all the time, and it would wake you up immediately if someone asked you to do something against your values and your interest. So, if you imitate a chicken, it's because in reality, you want to.

But I think that we have much more important things to do together: find the way to your happiness and your liberation. It's more useful, isn't it ?
