Well, as I said, you can overanalyze all you want, but it still works. I can say from my skeptical astronomer viewpoint that no wacky doctrines were imparted to me at any point - it was some very gentle visualizing. If I could go back to two years ago when I started hypno, I would tell myself that I can listen and think, but there's no secret message I need to ferret out of it. Oh, and drifting off a bit is rather enjoyable.
