I don't know of any similar files, so there probably should be one made. I've heard of the idea before (mostly in erotic fiction :roll:) so I have given a little thought on how to set that up (but as of yet I haven't done it).
And I have heard the theory that when someone responds to a trigger like that, that they're entering a light trance. Or any post-hypnotic suggestion, really. Like if hearing a certain phrase will make someone start itching, then the phrase may actually put them into trance while they're itching. So theoretically they're more suggestible in general while they're being triggered, even if the trigger isn't specifically intended to take them into trance.
Or so the theory goes :P
