The Backrooms began as an online creepypasta about endless, yellow, fluorescent-lit rooms, and quickly became a popular setting for horror videos, games and TikTok edits. This theme draws on the distorted, nostalgic piano style made famous by The Caretaker's It's Just a Burning Memory, which creators adopted because its fading melody mirrors the feeling of being lost in a familiar but empty place. As Backrooms content spread across YouTube and social media, the loop became shorthand for liminal dread, and editors still use it to signal that something ordinary has turned strange.
