The supernatural often casts an eerie light on reality. It glows in the darkness, and shines unlike the mundane experiences of anyone. As we tell stories with this glow, we emphasize the unnatural illumination and the dangers of the unknown. Ghosts have their [[SicklyGreenGlow glowing ectoplasm]], fairies have their BallOfLightTransformation, and possession may be marked by the GlowingEyesOfDoom.

* ''Series/HerculesTheLegendaryJourneys'': In ''Film/HerculesInTheUnderworld'', the entrance to the realm of Hades is a large hole that emits a column of green light, from which little green ghosts ascend.

[[folder:Tabletop Games]]
* ''TabletopGame/LegendOfTheFiveRings'' has the Shadowlands, where the dishonourable dead "live", but they can also enter the living world. Things from the Shadowlands have something called the [[TheCorruption Shadowlands Taint]], which can be used to poison living creatures. Those affected by the Taint glow a sickly green. However, blessed green jade is a reliable way to protect both one's soul from spiritual corruption and one's body from physical harm when dealing with the Shadowlands, and it gives off an apparently similar glow.

[[folder:Western Animation]]
* ''WesternAnimation/DannyPhantom'': Ghosts (and half-ghosts) usually have a white aura surrounding them in their ghost form. The stronger they are, the larger their aura.
