The Science of Unexplainable Presence: Understanding the Feeling of Not Being Alone.
Research explains the neuroscience behind the experience of feeling the presence of another when alone in an empty room. The Society for Psychical Research conducted one of the largest studies on the topic in 1894, concluding that such experiences happened too often to be down to chance. Presences have a particularly strong link with sleep paralysis, experienced by around 7% of adults at least once in their life. Studies have suggested more than 50% of people with sleep paralysis report encountering a presence. The experience of feeling a presence can be unnerving, but scientific research may give us an explanation for this phenomenon.
