Hallucinations in Parkinsons disease (PD) are one of the most common non-motor symptoms, affecting about half of all patients, and the most common form are presence hallucinations (PH). Some individuals with PD report sensing the presence of deceased loved ones, referred to as grief or bereavement hallucinations. In these experiences, people report feeling the presence, hearing, seeing, or otherwise perceiving a deceased person. We refer to them as "after death experiences" (ADEs). We analyzed the phenomenology of ADEs in six patients with PD. Relying on in-depth interviews, we describe the appearance and evolution of ADEs, their emotional aspects, how ADEs manifest, and how patients accounted for the experience. We report several similarities between ADEs in patients with PD and those in bereaved individuals (not related to PD), but also important differences. Patients with PD experience repeated ADEs. This reoccurrence allowed us to examine the way in which people make sense of these experiences by using both cognitive and reflective language. Our findings are not only of relevance for ADEs in PD, but also for a better understanding of ADEs in other contexts, allowing to form new hypotheses about ADEs and their social-cognitive mechanisms to inspire future behavioral and neurocognitive research.
