input: The Head Rap Method [Pentecostalism] Pentecostal preachers actually use this!!! They PUNCH people in the head with their palm as if they were serving a volley ball! The blow knocks the head back! The faith healer shouts all kinds of things at the point of contact, exactly like the hypnotists!
output: A sudden pain will often snap the subject into hypnosis. This method is related to the foregoing. Passing by a subject, suddenly catch his eye. You can tell when this occurs as his eyes set upon yourself on the instant with something of a surprised, bewildered blank look in their focus. Having captured such attention, suddenly snap the knuckles of your right hand with a rap (not too gentle) on the top of his head. At the moment of contact with the skull, shout, "SLEEP!" The subject will instantly snap into hypnosis. You can then soften things by suggesting: "The pain from the rap is all gone now, for you are in hypnosis. You feel all comfortable now. Go deep to sleep now in profound hypnosis" (Shadow's Stage Hypnosis)
