Braid created a rough distinction amongst various phases of hypnosis which he termed the main and 2nd mindful stage of hypnotism, he later replaced this with a difference concerning "sub-hypnotic", "full hypnotic", and "hypnotic coma" levels. Jean-Martin Charcot made an analogous difference in between stages named somnambulism, lethargy, and catalepsy. https://goo.gl/maps/5vjUhEDhdeq8xgw98
