The U.S. Naval Institute (which may refer to the broader U.S. Naval Academy) has several reported hauntings and paranormal phenomena, including apparitions of former patients and a Japanese pilot, cold spots, turning doorknobs, and an unseen presence. The institution's history as a Civil War hospital and formerly being home to the poor or mentally unstable contributes to these reports. The phenomena are often investigated on paranormal reality shows, such as Ghost Hunters, which document encounters with unseen forces and strange occurrences. The location was once used as a Civil War hospital and as a place for the mentally unstable and poor. Many people have died in the building, contributing to the belief that it is haunted. A former patient named Jimmy Sutton is said to haunt the location, with his alleged death in 1907 occurring after an argument over a woman. A Japanese pilot is believed by some to haunt the museum, with a black misty figure sometimes seen standing in a corner. Cold spots: and unexplained temperature changes have been reported. Unseen presences: are felt by people in rooms even when no one else is present. Sounds: such as loud voices, heavy breathing, and the stomping of boots have been heard. Doorknobs: have been observed turning on their own. Falling light fixtures: have been reported. An unseen force that attempts to push people down the stairs is also a reported phenomenon.
