The Backrooms

The Backrooms is an urban legend and creepypasta about a maze with no end that has empty office rooms in a moist yellow room and hallways. It is said to have the smell of wet carpet with the sound of buzzing lights. These rooms have levels with monsters and "entities" living in them. Usually people get into the backrooms by accidentally falling or no-clipping through any solid object in real life.
Since its original creation, The Backrooms has been expanded into other forms of media and Internet culture, including video games, memes, and a Horror / Science fiction web series .
