Hypnosis

[Foxy The Pirate]

Well not the stage shows it was like a audio clip a friend linked me and you do it by lying down and relaxing while listening to said audio clip and for example the audio clip i listened to was to make your brain believe you were like in an animal body and it goes through great detail of describing that your body changes and bones twist and turn and it really felt like it. But as Joey said i think its more likely to work if you believe it will work.
