The Roblox Error Code 1001 meme is a viral internet creepypasta that gained massive popularity on platforms like TikTok and YouTube. It centers around a fictitious, ominous error message that allegedly appears when a player is in danger, often accompanied by the chilling phrase 'Someone is in your house.' While the error code doesn't actually exist in the official Roblox platform, it has become a staple of 'analog horror' style content within the community. Users leverage the template to create suspenseful videos or jump-scare memes, playing on the shared anxiety of being watched while gaming late at night.
