 And in that book, the patient, Sybil, real name Shirley Mason, has a condition that works kind of like what you see in the TikTok videos, kind of like what you see in the movies. What was it? M. Night Shyamalan movie split where the guy has 15 different personalities and some of them are serial killers and some of them aren't. And so Shirley Mason, Sybil, had something sort of like that.
