A 20-year-old man was admitted to an inpatient psychiatric unit for self-professed dissociative identity disorder. His presentation of multiple personalities without amnesia, dissociation or depersonalisation led to further examination of personality and cultural factors that may contribute to this uncommon presentation. Careful clinical investigation supported a diagnosis of schizotypal personality disorder with elements of fantastical thinking influenced by media presentations of dissociative identity disorder.
