This scream is identified in its original listing as coming from a YouTube video featuring a stalker in the Backrooms, the empty, yellow-walled liminal-space setting that became a major online horror trend. Short, intense reaction sounds like this are often lifted from longer horror videos and shared on soundboards, where they take on a second life apart from the original footage. It remains popular because the Backrooms setting is instantly recognisable to horror fans, and a single human scream is easy to drop into edits, streams and memes without needing any context.
