Level 1 is the second layer of the Backrooms.
A picture of Level 1.
Description
Level 1 is roughly the same as Level 0, with a few major differences. The trigger to reach this level is seemingly completely unpredictable. At any point in the backrooms after at least 4 days, there's a chance the lights will begin to flicker on and off. Eventually the lights will turn off for minutes or hours at a time. While the lights are off this level is very dangerous. Interactions with beings in this level are very common and they are more nonhumanoid. They would usually come near when the lights are off and they are close when you can hear distorted noises nearby usually resembling screaming.
Exits
Although possible, it is difficult to re-enter Level 0 from Level 1. Level 2 can be accessed by certain stairs. Sometimes you will simply find yourself in Level 2 after spending enough time in the previous level.
Escape here is still possible through the exit points.
