Lisa

Lisa is a ghost that appears in P.T.. She was murdered with a rifle by her husband, shot in the right eye and in the stomach while pregnant. A message in the game implies he regretted murdering her as he claimed there was a "monster" inside of him, and he sought forgiveness from her. Lisa's husband may have killed himself afterwards. She haunts the hallway that is being repeatedly traversed by the protagonist, who is stuck in a loop. She has the ability to appear and disappear at will.
