Often referred to as the Hat Man, Shadow Figure, or Humanoid Black Mass, a Shadow Person is typically described as a very tall, solid black figure, that is typically in the form of a humanoid type of entity. The do not have a face, although sometimes arms and fingers are noticeable. They are seen arching in contorted stances but are not especially animated. They linger, and hover higher than a person would stand, often in the corner of a room, or at the end of a hallway. Some people describe them being eight feet or taller in height, and sometimes appear as tall as the ceiling of a room. Their size grows over time. Their lower body tends to morph into a solid black mass that blends in with, and bleeds into, the space they are occupying. So it’s mostly the torso and head that appear in human like form.[…]
