I don't think Dickson was limiting his search to real hypnotism.  Sounds like simulated hypnotism would suffice.

Usually the girl just goes to sleep or passes out and dreams what then happens.  Then wakes up at the end in bed.

The actual sex in porn isn't fake? (Vanilla porn)   When she starts carrying on as the dick first touches her, that's not Academy Award material?

Strictly from a Femdom scenario in much that I've already seen from a Dominatrix talented in Hypno Therapy or power of suggesstion seems somewhat boring unless someone gets off on listening to a Domme trying to mezmerize you over a telephone or video.

And I can't see how one would even classify this kind over entertainment as XXX porn itself. Far different if a hot sexy Mistress is physically dominating your mental faculty in your presence and in your being in bondage while being overwhelmed by the power of her demanding femininity. Amost all men including submissive men of course have a weakness of being very visual when it comes to the sensuality of a Mistress you know will dominate you in pain and pleasure. That's her specialty. One Mistress that comes to mind outside the realm of Kink.com is Mistress Candice. http://mistresscandice.com/  Nothing to say negative about her personally, but I've seen a number of her videos and wasn't the least enthralled.

I think in general using "hypnosis" scenes would probably deprive viewers of the true consent part of the scene. I think every now and again though it's probably nice to have a scene. Especially with relation to religion - traditional like Christianity or some sort of spiritual based one such as Wicca/one of the new age religions. It'd help with the idea that the girl was really engaging with the hypnosis if she was in a state of religious delirium.
