Why Inducing Hallucinations Might Be a Good Idea

Presence hallucinations involve perceiving someone nearby when no one is present. Researchers have developed methods to induce these hallucinations in a lab, which could aid in diagnosing conditions like Parkinson's disease. Two main methods are used: one involves audio recordings of participants, and the other uses a robotic arm to create sensory discrepancies. These methods help understand susceptibility to hallucinations, potentially leading to early diagnosis and treatment of neurological conditions.
