‘The Ghost Pushes You Down’: Sleep Paralysis-Type Panic Attacks in a Khmer Refugee Population

Abstract

Among a psychiatric population of Cambodian refugees (N = 100), 42% had current - i.e. at least once in the last year - sleep paralysis (SP). Of those experiencing SP, 91% (38/42) had visual hallucinations of an approaching being, and 100% (42/42) had panic attacks. Among patients with post-traumatic stress disorder (PTSD; n = 45), 67% (30/45) had SP, whereas among those without PTSD, only 22.4% (11/45) had SP (χ² = 20.4, p < .001). Of the patients with PTSD, 60% (27/45) had monthly episodes of SP. The Cambodian panic response to SP seems to be greatly heightened by elaborate cultural ideas - with SP generating concerns about physical status, ‘good luck’ status,‘bad luck’ status, sorcery assault, and ghost assault - and by trauma associations to the figure seen in SP. Case vignettes illustrate cultural beliefs about, and trauma resonances of, SP. A model to explain the high rate of SP in this population is presented. SP is a core aspect of the Cambodian refugees response to trauma; when assessing Cambodian refugees, and traumatized refugees in general, clinicians should assess for its presence.
