Image of Level 387
Level 387 is a blank room with nothing but a chair and a locked door. To enter this level, one must commit a serious crime within the Backrooms. For instance, killing humans for fun or destroying a level. You cannot be sent here if you're being chased by an entity, for that is an easy escape to be safe for a while. In order to exit Level 387 you must sit in the chair and think about what you did for 24 hours, as if you were in timeout as a child. As soon as the 24 hours have passed, the door will unlock and you may exit the level. There are said to be iterations of this room for everyone in the Backrooms.
