Rave goers have known for years that the powerful combination of loud music and drugs could put someone into a state of trance, where the setting drifts into the background and a feeling of overwhelming connection and love comes to the foreground. In the sixties and seventies, it was new age music that created this hypnosis meditation. Before that, shamans mesmerized themselves around the fire to the sound of drumbeats. Techno trance therapy has been taught in various workshops from London to California but is primarily a form of self-hypnosis that people teach themselves.
