Ukamairinek (Inuktitut pronunciation: [?] , referred to by patients as soul loss, soul possession, or soul wandering) is a culture-specific disorder occurring among Inuit in the circumpolar regions, characterised by sleep paralysis accompanied by restlessness, anxiety and hallucinations. [1] [2] [3] Prodromal indicators of the condition are transient hallucinatory odours or sounds. Research has described the syndrome as a dissociation reaction, or a possible narcolepsy-cataplexy syndrome. The syndrome concludes with complete remission, usually within a few minutes. It is coded under ICD-10 as F44.88 and G47.4. [4]
