Level 6 is an expansive complex of indeterminate size, made up of metallic walls, brick floors, and complex systems of pipes. The entirety of Level 6 is shrouded in complete darkness; thus far, no light sources have successfully created any light in the level. Due to the level's darkness, it is not possible to take sufficient photographs of it.
Auditory hallucinations are frequently experienced in Level 6, ranging from rushing water to indecipherable voices ringing throughout the piping. It is believed Level 6 may be able to influence one's perception of reality, resulting in symptoms of paranoia and derealization. Despite possessing no known tangible threats, Level 6 is regarded as being one of the most dangerous levels in the Backrooms because of its sheer darkness. A significant portion of the Wanderers that enter this level permanently lose their sanity or go missing.
