Among DID individuals, the sharing of conscious awareness between alters exists in varying degrees. I have seen cases where there has appeared to be no amnestic barriers between individual alters, where the host and alters appeared to be fully cognizant of each other. On the other hand, I have seen cases where the host was absolutely unaware of any alters despite clear evidence of their presence. In those cases, while the host was not aware of the alters, there were alters with an awareness of the host as well as having some limited awareness of at least a few other alters. So, according to my experience, there is a spectrum of shared consciousness in DID patients. From a therapeutic point of view, while treatment of patients without amnestic barriers differs in some ways from treatment of those with such barriers, the fundamental goal of therapy is the same: to support the healing of the early childhood trauma that gave rise to the dissociation and its attendant alters.Good DID therapy involves promoting co­-consciousness. With co-­consciousness, it is possible to begin teaching the patient’s system the value of cooperation among the alters. Enjoin them to emulate the spirit of a champion football team, with each member utilizing their full potential and working together to achieve a common goal.Returning to the patients that seemed to lack amnestic barriers, it is important to understand that such co-consciousness did not mean that the host and alters were well-­coordinated or living in harmony. If they were all in harmony, there would be no “dis­ease.” There would be little likelihood of a need or even desire for psychiatric intervention. It is when there is conflict between the host and/or among alters that treatment is needed.
Some alters are what Dr Ross describes in Multiple Personality Disorder as 'fragments'. which are 'relatively limited psychic states that express only one feeling, hold one memory, or carry out a limited task in the person's life. A fragment might be a frightened child who holds the memory of one particular abuse incident.' In complex multiples, Dr Ross continues, the 'personalities are relatively full-bodied, complete states capable of a range of emotions and behaviours.' The alters will have 'executive control some substantial amount of time over the person's life'. He stresses, and I repeat his emphasis, 'Complex MPD with over 15 alter personalities and complicated amnesia barriers are associated with 100 percent frequency of childhood physical, sexual and emotional abuse.' 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.
