Description
What does it mean to sense something that isn’t there? Join psychologist and author, Ben Alderson-Day, for a fascinating exploration of the unseen – from voices heard by people with psychosis, to the invisible companions of children, and the deeply felt presences reported in spiritual or paranormal experiences.
Drawing on his acclaimed book Presence, Alderson-Day blends cutting-edge neuroscience with compelling case studies to examine how the brain constructs our sense of reality.
This thought-provoking event asks where perception ends and imagination begins, and what these blurred boundaries reveal about the mysteries of the human mind.
