Presence: The Strange Science and True Stories of the Unseen Other (English Edition)

A psychologist's journey to understand one of the most unusual experiences known to humankind: the universal, disturbing feeling that someone or something is there when we are alone. These experiences of sensing a Presence when no one else is there have been given many namesthe Third Man, guardian angels, shadow figures, social hallucinationsand they have inspired, unsettled, and confounded in equal measure. While the contexts in which they occur are diverse, they are united by a distinct and uncanny feeling of visitation by another. But what does this feeling mean, and where does it come from? When and why do presences emerge? And how can we even begin to understand a phenomenon that can be transformative for those who experience it, and yet so hard to put into words? The answers to these questions lie in this tour-de-force through contemporary psychology, psychiatry, neuroscience, and philosophy. Presence follows Ben Alderson-Day's attemptsas a psychologist and a researcherto understand how this experience is possible. What is a voice when it isnt heard, and how otherwise do we know or feel that someone is in our presence? Is it a hallucination connected to psychosis, a change in the working of the brain, or something else? The journey to understand takes us to meet explorers, mediums, and robots, and step through real, imagined, and virtual worlds. Presence is the story of who we carry with us, at all times, as parts of ourselves.
