Eh, what I can recall of my dreams are narrative messes full of individual moments that usually aren't tied together with a coherent plot, but, yes, hypnosis does figure prominently in my dreams in one of at least three ways:
1) I have the power that those guys have in DARK CITY where I can just say "Sleep" and have most people nearby fall asleep and be under my control, usually for uninhibited sexy time purposes, although sometimes there will be people that resist and I'm immediately paranoid about getting caught doing something naughty. Even though I wouldn't call DARK CITY one of my favourite movies, it did have a profound effect on my dreams, more so than any other movie I can think of off-hand, possibly since the city was like a literal dream in many ways, especially how things constantly change just like my actual dreams.
2) I'm watching some kind of mass stage hypnosis show with far more people on stage than would actually be on stage at a hypnosis show, or the entire audience is under hypnosis or something.
3) Occasionally, I'll dream about being hypnotized, usually in some kind of venue you wouldn't generally associate with hypnosis, like a shopping centre or a subway station. Weirdly, even though, in real life, I'm pretty much only interested in being hypnotized and not really in being the hypnotist, the dreams where I'm the subject are vastly outnumbered by dreams where I'm the hypnotist or observing a hypnotist.
One thing about hypnosis dreams that's changed over the years: when I was in my late teens through my twenties, dreams about hypnosis usually ended abruptly and I'd wake up immediately with sticky underwear or pajamas, if you catch my drift. But now that I'm in my late thirties, I rarely have "nocturnal missions", as Beavis and Butthead would put it, at all, probably due to several factors: a) I'm older and my libido is under control compared to how it was when I was a young adult, b) I've been listening to hypnosis mp3s for over a decade now and, while I still have undeniable erotic associations with hypnosis (I wouldn't be here if I didn't), it's not the instant hard-on generator it was for me as a younger person because I have been desensitized to hypnosis significantly because of experience and familiarity with it, and c) I'm on certain prescription drugs with side effects that interfere with some sexual responses so it's simply a lot harder for me to get over the edge, if you catch my drift again.
