The programme into which Cheryl was inducted combined all the different ways the intelligence community had learned could cause intense psychological change in adults and children. It had been learned through the use of both knowledgeable and 'unwitting' volunteers. They were subjected to sensory overload, isolation, drugs and hypnosis, all used on bodies that had been weakened from mild hunger. The horror of the programme was that it would be like having an elementary school sex education class conducted by a paedophile rapist. It would have been banned had the American government signed the Helsinki Accords. But, of course, they hadn't.
For the test that day and in those that followed, Cheryl Hersha was positioned so she faced a portable movie screen. A 16mm movie projector was on a platform, along with several reels of film. Each was a short pornographic film meant to make her aware of sexuality in a variety of forms...

Other personalities are created to handle new traumas, their existence usually occurring one at a time. Each has a singular purpose and is totally focused on that task. The important aspect of the mind's extreme dissociation is that each ego state is totally without knowledge of the other. Because of this, the researchers for the CIA and the Department of Defense believed they could take a personality, train him or her to be a killer and no other ego stares would be aware of the violence that was taking place. The personality running the body would be genuinely unaware of the deaths another personality was causing. Even torture could not expose the with, because the personality experiencing the torture would have no awareness of the information being sought.
Earlier, such knowledge was gained from therapists working with adults who had multiple personalities. The earliest pioneers in the field, such as Dr. Ralph Alison, a psychiatrist then living in Santa Cruz, California, were helping victims of severe early childhood trauma. Because there were no protocols for treatment, the pioneers made careful notes, publishing their discoveries so other therapists would understand how to help these rare cases. By 1965, the information was fairly extensive, including the knowledge that only unusually intelligent children become multiple personalities and that sexual trauma endured by a restrained child under the age of seven is the most common way to induce hysteric dissociation.

We must understand that those who experience abuse as children, and particularly those who experience incest, almost invariably suffer from a profound sense of guilt and shame that is not meliorated merely by unearthing memories or focusing on the content of traumatic material. It is not enough to just remember. Nor is achieving a sense of wholeness and peace necessarily accomplished by either placing blame on others or by forgiving those we perceive as having wronged us. It is achieved through understanding, acceptance, and reinvention of the self.
At this point in time there are people who question the validity of the DID diagnosis. The fact is that DID has its own category in the Diagnostic and Statistical Manual of Mental Disorders because, as with all psychiatric conditions, a portion of society experiences a cluster of recognizable symptoms that are not better accounted for by any other diagnosis.

Did I imagine the castle, the dungeon, the ritual orgies and violations? Did Lucy, Billy, Samuel, Eliza, Shirley and Kato make it all up?
I went back to the industrial estate and found the castle. It was an old factory that had burned to the ground, but the charred ruins of the basement remained. I closed my eyes and could see the black candles, the dancing shadows, the inverted pentagram, the people chanting through hooded robes. I could see myself among other children being abused in ways that defy imagination. I have no doubt now that the cult of devil worshippers was nothing more than a ring of paedophiles, the satanic paraphernalia a cover for their true lusts: the innocent bodies of young children.

In the same way that the women's movement of the seventies and eighties brought rape and incest into public consciousness, we can do the same with the causes and reality of dissociation and multiplicity.

Dr. Talbon was struck by another very important thing. It all hung together. The stories Cheryl told — even though it was upsetting to think people could do stuff like that — they were not disjointed They were not repetitive in terms of "I've heard this before". It was not just she'd someone trying consciously or unconsciously to get attention. really processed them out and was done with them. She didn't come up with them again [after telling the story once and dealing with it]. Once it was done, it was done. And I think that was probably the biggest factor for me in her believability. I got no sense that she was using these stories to make herself a really interesting person to me so I'd really want to work with her, or something. Or that she was just living in this stuff like it was her life. Once she dealt with it and processed it, it was gone. We just went on to other things. 'Throughout the whole thing, emotionally Cheryl was getting her life together. Parts of her were integrating where she could say,"I have a sense that some particular alter has folded in with some basic alter", and she didn't bring it up again. She didn't say that this alter has reappeared to cause more problems. That just didn't happen. The therapist had learned from training and experience that when real integration occurs, it is permanent and the patient moves on.
