In this chapter I restrict myself to exploring the nature of the amnesia which is reported between personality states in most people who are diagnosed with DID. Note that this is not an explicit diagnostic criterion, although such amnesia features strongly in the public view of DID, particularly in the form of the fugue-like conditions depicted in films of the condition, such as The Three Faces of Eve (1957). Typically, when one personality state, or ‘alter’, takes over from another, they have no idea what happened just before. They report having lost time, and often will have no idea where they are or how they got there. However, this is not a universal feature of DID. It happens that with certain individuals with DID, one personality state can retrieve what happened when another was in control. In other cases we have what is described as ‘co-consciousness’ where one personality state can apparently monitor what is happening when another personality state is in control and, in certain circumstances, can take over the conversation.

After a few sips, he picked up his sax and started jamming with the storm.Most days, Rivers meditated twice, when he awoke and again in the evening before writing or reading. But he still found a special relaxation and renewal in solitary playing. Contemplation through music was different from other reflective experiences, in part, because his visual associations were set free to mutate, morph, and meander; while the other senses were occupied in fierce concentraction on breathing, blowing, fingering, and listening. Within the flow of this activity, his awareness would land in different states of consciousness, different phases of time, and easily moved between revisualization of experience and its creation.The playing dislodged hidden feelings, primed him for recognizing the habitually denied, sheathed the sword of lnaguage, and loosened the shield and armor of his character. His contemplative playing purged him of worrisome realities, smelted off from his center the dross of eperience, and on those rare and cherished days, left only the refinement of flickering fire. Although he was more aware of his emotions, the music and dance of thought kept them at arm’s length, Wordsworth’s “emotion recollected in tranquility.” . . .As he played, his mind’s eye became the fisher’s bobber, guided by a line of sound around the driftwood of thought, the residue of his life, which materialized from nowhere and sank back into nothingness without his weaving them into any insistent pattern of order and understanding. He was momentarily freed of logical sequencing, the press of premises, the psycho-logic of primary process, the throb of Thought pulsing in and through him, and in billions of mind/bodies, now and throughout time, belonging each to each, to none, to no one, to Everyone, rocking back and forward in an ebb and flow of wishes, fears, and goals. He fished free of desire, illusion, or multiplicity; distant from the hook, the fisher, the fish; but tethered still on the long line of music, until it snagged on an immovable object, some unquestioned assumption, or perhaps a stray consummation, a catch in the flow of creation and wonder.

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.
