Dr Jeni Haynes has 2682 people in her mind. She’s now telling how she lives with her ‘alters’

Dr Jeni Haynes has spent her life trying to make people believe what is, to many, unbelievable: that she has 2682 people inside her mind. Haynes was diagnosed with dissociative identity disorder (DID), formerly known as multiple personality disorder (MPD), a decade before she took the stand in a 2019 trial in a Sydney court that put her father, Richard Haynes, behind bars for 45 years. Setting a legal precedent, six of her alternate personalities, or “alters”, gave evidence, recalling in photographic detail the abuse, rape and torture she endured throughout her childhood.

“We’re perfectly sane people using an incredible survival strategy to survive what should be un-survivable,” says the Entity Currently Known as Jeni, as she introduces herself in the groundbreaking SBS documentary We Are Jeni. She uses the pronouns “we, us and our” to acknowledge that all her alters are always present. They include protective Erik; leather-clad Muscles; and four-year-old Symphony, the original alter who created the entire “constellation”.

“The only way I survived my dad was being able to switch into different alters,” says Haynes. “Because every time somebody got too exhausted from what he was doing, we switched them out and sent somebody else in, like shoving in a new battery.”

She gets that DID is difficult to grasp, even for those who have it. She spent 18 years in academia, studying psychology (“to find out what was wrong with me”); criminology (“to find out whether what he did was criminal”); and completing a PhD in male victimology (“to stop me being afraid of half the population”).

When approached by filmmakers Mariel Thomas and Akhim Dev, she seized the opportunity to tell her story in her own words. In We Are Jeni, she presents confronting truths and dispels myths. Classic movies such as The Three Faces of Eve and Sybil filter DID through the eyes of therapists, she says, hiding the experience “behind innuendo and euphemism”.

She turned off the 2009 Toni Collette series, United States of Tara, after five minutes, triggered by a “sexy” alter. However, her psychiatrist, Dr George Blair-West, who appears in the documentary and with whom Haynes co-authored her memoir, The Girl in the Green Dress, declined to watch the series because he found it too realistic, “like work”.

Also appearing in the documentary is the man Haynes calls “God on legs”, NSW Police detective Paul Stamoulis. “He listened, and then he went out and got evidence.”

Reliving her trauma for the documentary came at a cost. “There were days when we cried. There were days when we could only thin
