SCP: Secret Laboratory is a multiplayer horror game inspired by the SCP Foundation collaborative fiction project, where players take roles inside a containment facility during a breach. Short in-game effects like this Ghostlight clip are ripped and shared on soundboards because they are instantly recognisable to players and easy to reuse outside the game. Online, the sound has spread as a compact horror cue for edits, streams and meme videos, where its connection to SCP lore gives a simple flash or reveal a more ominous, supernatural meaning.
