Extremely confusing tunnels

stumbled on a door that led to tunnels

the wifi got so bad down there that i started panicking and tried to find a way out

all doors were locked so i ended up walking for around two days

had no clue if i was somewhere underground, the air was cold and everywhere was quiet.

every now and then i'd look behind me to check if something is following me or if the walls started shifting behind me

sometimes there are open doors that lead to this tiny maintenance room (i think), the holes sometimes have lights in them but i dont think they lead anywhere, i dropped a pen down and i didnt hear it ever again. Im assuming its just a bottomless pit.

hoping i get out of here soon
