The sound comes from The Rake, a Roblox horror game inspired by the creepypasta creature of the same name. In the game, Blood Hour is a rare event where the Rake becomes faster and far more aggressive, and its scream marks an attack or nearby presence. Players clipped the shriek from gameplay and shared it on soundboards for use outside the game. It is often grouped with the FNAF jumpscare scream in horror sound collections because both rely on a sudden, piercing wail to startle viewers.
