A new case study in Cortex by neurologist Dr. Fabienne Picard (2010) reports on a patient who experienced unusual phenomena during epileptic seizures. She had the convincing sense that several familiar people (family members) were standing before her. This experience of a “sensed presence” is a classic trope in movies with supernatural themes (e.g., Carnival of Souls [available at Internet Archive], The Haunting [trailer for the 1963 version], Poltergeist, Dark Water), but it’s generally attributed to ghosts and not to seizure activity.
From the report:
A 62-year-old right-handed woman of normal psychiatric history presented a simple focal epileptic seizure including a complex sensation characterized by feeling the presence of several members of her family in the immediate environment, associated with paresthesia of the right hemibody (excluding the face). The feeling of presences and the paresthesia (numbness) appeared concomitantly and lasted in total several minutes. The episode occurred while she was sitting alone on the sofa of her living room and immediately felt the presence of four persons in her frontal space. She did not see or hear these persons (no visual or auditory hallucinations), but felt vividly their presence in her peripersonal [within reach] and near extrapersonal space [just outside of reach]. She “recognized” them as close family members. Closest was her grand-daughter who was sitting on the floor immediately in front of her, without any left or right lateralization in relation to her body, whereas the three other persons, her daughter and two other grand-children, were experienced to be localized at a distance of several meters. … This highly vivid and convincing feeling of presences was described by the patient as deeply pleasant, although she guessed that it was not possible that they were really there, as she was alone just before. … She was treated with pregabalin (300 mg/day) and there was no recurrence of simple or complex partial seizures and no further feeling of presences.
