The backrooms

If you're not careful and accidentally teleport out of reality in the wrong areas, youll end up in the backrooms. Here, it is nothing but the stink of old, moist carpet, the madness of mono-yellow, the endless backround noise of fluorescent lights at maximum hum-buzz, and about 800 million square miles of randomly connected empty rooms where you are trapped. God save you if you hear something wandering around, because by that point, it already knows you are there.

Someone help, ive teleported to the backrooms.

The Backrooms

The Backrooms is a realm that first appeared on 4Chan. This realm is out of the boundaries of the real world and can only be accessed by nocliping through a floor or wall in a place that inspires deja vu or an uncomfortable feeling of nostalgia. It consists of a never-ending maze of yellow-ish empty rooms with beige carpets, old wallpaper, the smell of mildew and moldy carpets, and the faint buzz of fluorescent lighting.

Someone please kill me I’ve been in the backrooms for so long I just want to die
