The Backrooms
The Backrooms began as an internet creepypasta — noclip through reality and you land in endless damp yellow office corridors — and grew into shorthand for any impossible interior: hallways that should not fit inside the building, doors that open onto rooms nobody built. What keeps the idea alive on a TRUE-story site is the steady trickle of accounts from janitors, security guards and urban explorers who mapped a basement one door too long. The jury usually votes fake. Usually.
