Dear Arturo:
Welcome to the forum and your questions are excellent.
Certainly a degree of self-hypnosis can be a part of this journey. But as with many things in life.... they are not what they appear to be. In my experience there is a deep hypnosis which has occurred through and by society, education, peers, governments, etc. and at it's deeper foundation lies Maya/ego. Much of the Nav Series is about de-hypnosis, awakening someone from their trance. You may well be running yourself through some illusory experiences in an effort to mimic my, and other's, experiences. However this can be a good way to stretch yourself into other possibilities. If you didn't think that H/A and T/R were at least a possibility they you would not put any effort into them. Thinking they are possible could be seen as a mild form or hypnosis.
You mentioned that most of your ''experiences'' came when you were doing something else, not efforting, and that is very common. It's like not being able to remember something, but when you give up a few moments later it comes to you clear as day. Growth in this arena can be gradual. You study something diligently and don't think you have made any headway and then when you throw up your hands and get on with life you find your experiences are different, you don't react the same way.
This is progress and you are, IMHO, doing just fine doing what you are doing. Stick with it, do whatever you do with all your heart, and then throw it away for a while.
Love ya, Jed
