Endorsement of and identification with cultural beliefs about spirit possession can affect clinical presentations and explanatory models associated with sudden, uncontrollable behavior. Although literature shows links between possession-form presentations and dissociative disorders, which is also a focus of this paper, few studies explore in detail the experiences, meaning-making, and coping strategies of people with such presentations. This study is an interpretative phenomenological analysis of changes in behavior and identity reported by an elderly, Catholic Mauritian woman of a Tamil background during in-depth interviews. The participant shared her personal experiences in relation to acquired beliefs about the influence of the supranatural world. In this study, such explanations — whether they have a dissociative base or not — are regarded as cultural metaphors to rationalise her conflicting impulses and actions. We suggest that possession-form presentations may involve various diagnoses and psychological strategies. The need for further research into possession-form presentations using detailed clinical diagnostic assessment is emphasised. This study also questions the link between possession-form presentations and complex dissociative disorders.
