I'm guessing the one by Forbes Blair? Cuz that one's a total rip off.

And also everybody (exclduing abnormal mental condition) is susceptible to hypnosis it's just that the depth of trance varies but you could change that by practicing fractionation.

Yep. I’m all into hypnosis. I even got this plan to log on over 3 hundred hours of inductions or until I've achieve neg. hallucination. So far I've only got less than 5 hrs.

I even have this theory that lucid dreaming is achieved becuz of hypnosis. You get into a trance state to bypass you conscious critcal factor and using autosuggestion establishes the selective thinking or maybe even your expectations itself causes it. The transition from wake to sleep or vice versa is actually a light trance state.
