A terrifying hallucination during sleep paralysis, once blamed on demons, now understood as a quirk of waking brain chemistry.
means A frightening sense of a malevolent presence pressing on your chest while you're awake but unable to move, now understood as sleep paralysis with hallucination rather than an actual visitor.
from 'Hag' traces back to Old English 'hægtesse,' meaning witch or female demon, related to words for fence or hedge — a creature that haunted the boundary between worlds. For centuries, cultures worldwide independently described a night-visiting entity that sat on sleepers' chests and stole their breath and movement — the 'mare' in nightmare is this same hag, not a horse. The phrase 'night hag' simply names that folkloric tormentor directly, and modern sleep science later explained the experience as paralysis occurring at the edge of REM sleep, with the mind's fear centers conjuring a face for the terror.
