A shadow person (also known as a shadow figure or black mass) is a popular subject in circles of the paranormal and supernatural detailing beings resembling animate human shadows, sometimes interpreted as the presence of a
spirit.
History and folklore

The ''
Coast to Coast AM'' late night radio talk show helped popularize modern beliefs in shadow people.
The first time the topic of shadow people was discussed at length on the program was April 12, 2001, when host
Art Bell interviewed a man pretending to be a
Native American elder,
Thunder Strikes, who is also known as Harley "SwiftDeer" Reagan. During the show, listeners were encouraged to submit drawings of shadow people that they had seen and a large number of these drawings were immediately shared publicly on the show's website.
In October that year, Heidi Hollis published her first book on the topic of shadow people, and later became a regular guest on ''Coast to Coast''. Hollis describes shadow people as dark silhouettes with human shapes and profiles that flicker in and out of peripheral vision, and claims that people have reported the figures attempting to "jump on their chest and choke them". She believes the figures to be negative aliens that can be repelled by various means, including invoking "the
Name of Jesus".
Although participants in online discussion forums devoted to
paranormal and supernatural topics describe them as menacing, other believers and paranormal authors do not agree whether shadow people are either evil, helpful, or neutral, and some even speculate that shadow people may be the extra-dimensional inhabitants of another universe.
Some
paranormal investigators and authors such as Chad Stambaugh claim to have recorded images of shadow people on video.
Shadow people feature in two episodes of
ITV paranormal documentary series ''
Extreme Ghost Stories'', where the phenomenon is described as a "black mass".
The "Hat Man"
One example of a particular shadow person is the "Hat Man", who shares the characteristics of general shadow people but is named for a
fedora or other brimmed hat on his head. Descriptions of the Hat Man date back to as early as the late 2000s.
The Hat Man is commonly associated with
sleep paralysis and the abuse of the antihistamine medicine

Psychiatrist Jack Potts suggests that methamphetamine usage adds a "conspiratorial component" to the sleep deprivation hallucinations.
One interviewed subject said that "You don't see shadow dogs or shadow birds or shadow cars. You see shadow people. Standing in doorways, walking behind you, coming at you on the sidewalk."
These hallucinations have been directly compared to the paranormal entities described in folklore.

In popular culture
* An episode of the
1985 ''Twilight Zone'' series titled "

* In the 1998 video game ''
LSD: Dream Emulator'', a humanoid figure commonly known as the Gray Man may appear in some dreams, who, if touched, undoes all dream progress and erases saved flashback data. The figure, in both appearance and roles in dreams, is similar to that of the "Hat Man" phenomenon.
