The return of the voices would end in a migraine that made my whole body throb. I could do nothing except lie in a blacked-out room waiting for the voices to get infected by the pains in my head and clear off.

Knowing I was different with my OCD, anorexia and the voices that no one else seemed to hear made me feel isolated, disconnected. I took everything too seriously. I analysed things to death. I turned every word, and the intonation of every word over in my mind trying to decide exactly what it meant, whether there was a subtext or an implied criticism. I tried to recall the expressions on people’s faces, how those expressions changed, what they meant, whether what they said and the look on their faces matched and were therefore genuine or whether it was a sham, the kind word touched by irony or sarcasm, the smile that means pity.
When people looked at me closely could they see the little girl in my head, being abused in those pornographic clips projected behind my eyes?
That is what I would often be thinking and such thoughts ate away at the façade of self-confidence I was constantly raising and repairing.

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.

Why do I take a blade and slash my arms? Why do I drink myself into a stupor? Why do I swallow bottles of pills and end up in A&E having my stomach pumped? Am I seeking attention? Showing off? The pain of the cuts releases the mental pain of the memories, but the pain of healing lasts weeks. After every self-harming or overdosing incident I run the risk of being sectioned and returned to a psychiatric institution, a harrowing prospect I would not recommend to anyone.
So, why do I do it? I don't. If I had power over the alters, I'd stop them. I don't have that power. When they are out, they're out. I experience blank spells and lose time, consciousness, dignity. If I, Alice Jamieson, wanted attention, I would have completed my PhD and started to climb the academic career ladder. Flaunting the label 'doctor' is more attention-grabbing that lying drained of hope in hospital with steri-strips up your arms and the vile taste of liquid charcoal absorbing the chemicals in your stomach.
In most things we do, we anticipate some reward or payment. We study for status and to get better jobs; we work for money; our children are little mirrors of our social standing; the charity donation and trip to Oxfam make us feel good. Every kindness carries the potential gift of a responding kindness: you reap what you sow. There is no advantage in my harming myself; no reason for me to invent delusional memories of incest and ritual abuse. There is nothing to be gained in an A&E department.

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.'

It is hard to bring paedophile rings to justice. Thankfully it does happen. Perhaps the most horrific recent case came before the High Court in Edinburgh in June 2007. It involved a mother who stood by and watched as her daughter of nine was gang-raped by members of a paedophile ring at her home in Granton, in the north of Edinburgh. The mother, Caroline Dunsmore, had allowed her two daughters to be used in this way from the age of five. Sentencing Dunsmore to twelve years in prison judge, Lord Malcolm, said he would take into account public revulsion at the grievous crimes against the two girls. He told the forty-three-year-old woman: 'It is hard to imagine a more grievous breach of trust on the part of a mother towards her child.' Morris Petch and John O'Flaherty were also jailed for taking part in raping the children. Child abuse nearly always takes place at home and members of the family are usually involved.

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.
