Shadow people (also known as shadow men or shadow beings) are a supernatural phenomenon reported by some individuals. Most accounts of shadow people describe them as black humanoid silhouettes, lacking mouths or eyes, although they are sometimes reported to have red or yellow eyes. They are generally described as lacking mass, although their specific nature varies from two-dimensional (like a shadow) to vaporous or distorted. Their movement is often reported as being very quick and disjointed, or “jiggly”, in the sense that they first may move slowly like a fluid (similar to jello rather than water), then rapidly “hop” to another part of a witness’ surroundings. Some witnesses describe this movement as though the shadow entities they have seen “danced” from one wall to the next. Some witnesses also claim to have been attacked, resulting in scratches, bruises, or burns.
