What is MindQuake? MindQuake is an educational event for people who are interested in erotic hypnosis, BDSM, and related activities. We offer classes on a broad range of topics including basic to advanced hypnosis techniques, erotic uses of hypnosis, using hypnosis as part of BDSM play, and more. Play parties give attendees an opportunity to use what they’ve learned, and we provide a dungeon environment for BDSM play as well.
