A trance trigger is usually a word or sentence that will bring you back into trance very quickly by itself. It could be a song, a specific touch, or almost anything else that’s distinctive. Normally, it’s set so that it only works when the hypnotist says the trigger word or does the special action. Post-Hypnotic Triggers can also be set to do other interesting things, like re-living an orgasm or feeling like the most confident time of your life. Or, conversely, timid and obedient, if you’re into that kind of game. They can also be made so that specified people can use these triggers. Setting them so *anyone* can use them is a little risky…

“Post Hypnotic” means “something that happens after trance”.
