The Shadow Person

Humanoid, solid black, no discernible features, often described as darker than the surrounding darkness. Frequently peripheral: seen from the corner of the eye and gone on looking directly.

Some accounts specify red or glowing eyes. That detail correlates strongly with prior exposure to the online material and should be treated with particular caution.

Watches. Stands still. Moves quickly when observed directly. Passes through doorways. Rarely interacts and almost never speaks.

Bedrooms overwhelmingly, at the sleep-wake boundary. Also hallways and peripheral vision in low light while awake, which places some reports outside dreaming altogether.

1. Waking, or lying awake in low light.
2. A dark shape noticed, usually peripherally.
3. Fear disproportionate to a shape.
4. The figure gone on direct inspection, or the episode ending with full waking.

Dread and a sense of malevolent attention. Reports emphasise being noticed back.

Dark-figure sleep experiences are ancient and are documented within the sleep-paralysis traditions.

"Shadow people" as a named, characterised category traces to internet forums and paranormal broadcast media from roughly the late 1990s onward. The name and the standardised description are recent.

Reports are now global and heavily concentrated in English-language online communities, which is what you would expect of a description spread by media rather than of an independently occurring phenomenon.

The Hat Man is treated as a distinct figure in the community material and has its own entry here, with the same caution applied.

Reports vary on whether the figure is peripheral or directly seen, and on whether the dreamer was paralysed. That second variable matters and is under-recorded: a shadow figure during sleep paralysis and a shadow figure in an ordinary dream are different claims.

• Sleep paralysis, underneath.
• Peripheral vision artefacts, in the waking reports.
• Cultural assembly of a figure from a physiological experience.
• Priming, and its effect on hallucinated content.

Little. The useful outcome is understanding the mechanism.

Sustained fear of the bedroom, which is reported and which affects sleep, creating exactly the sleep deprivation that makes further episodes more likely.

Priming effects on hallucinatory content are well documented in general. Expectation shapes what an ambiguous percept resolves into, and a person who has read detailed accounts of shadow people has been supplied with a template.

Peripheral vision is poor at form and good at motion, which accounts for the "seen at the edge, gone when looked at" structure without requiring anything else.

The modern figure is a genuine piece of contemporary folklore and worth documenting as such, which is a different project from documenting a shared dream entity, and this page keeps the two apart.

Sleep-paralysis hallucination accounts for the sleep-boundary reports. Peripheral-vision characteristics account for many waking ones. Priming accounts for the consistency of the description.

No evidence supports an external entity, and no mechanism has been proposed that would.

• Had you heard of shadow people before your first experience? The question this entry turns on.
• Could you move?
• Was it peripheral or directly seen?
• Were you asleep, waking, or awake?

Track against the sleep log rather than the dream journal. Sleep debt and irregular schedules are the reliable predictors.
