there is no one in the world who can't be hypnotized.
that is because hypnosis is a natural state of the mind, of high concentration and total awareness in your own being, also now as the alpha state of mind. The hypnotists is only helping the person to go into that state, but everybody already does that naturaly without naming it. is when you a to obsessed on your own toughts, on some kind of pain, for example. all hypnosis is just self hypnosis, the hypnotist is just catalizing this process, and that is the thing that can be a problem for aspies. in need to do that, he have to build rapport with hus subject, trought voice tonalites, body language, and basically an imense use of theory of mind to get the person into trace, which is much harder to do with an aspie, than with an nt.
so, we aren't good subjects for stage hypnosis, but on clinical hypnosis, where there is time, pacience and no audience, an aspie can be hypnotize without any problem.
