Ooooh, now that's a good question. I don't often see hypnosis wherein your own body betrays you, and that's hot. Maybe it's telling you to get pregnant, maybe it's telling you to breed, maybe you are hit with a sudden genetic imperative to work out, or eat, whatever, but your own body somehow being at odds with your brain and the chemicals it releases to make it fall in line is something I don't often see.

That, and singing. Very little hypnosis via song, which seems pretty obvious to me.
