I've had one hypnotist tell me that it gets in there no matter if you listen/concentrate or not, but I had another one tell me that it doesn't work if you fall asleep because you HAVE to listen and concentrate, so, go figure. :-/

I really would like to know if it is still effective when we sleep. I normally do not sleep deeply, I rather doze and often hear some parts of the hypnosis but then there are parts I do not remember. And I am awake when he says "I am going to wake you...".

Research shows that hypnosis (+ subliminals) have no effect when sleeping. Your sub conscious cannot receive a message if your conscious mind can't. When asleep your brain is in hibernation mode.

However you don't need to concentrate when listening, your thoughts can drift elsewhere and your sub conscious will still perceive the communication.
