There's this YouTuber who explores abandoned buildings,
and a video where they found a dungeon-like place under a shopping mall
just completely blew up in views.
The comments are going wild, calling it a real-life Backrooms.
*What are the Backrooms?

It's like this lol
You wake up in an endless
series of rooms, and no matter how far you go, there's no exit.
There's nobody in the vast space,
and occasionally monsters appear and threaten you.
>>> There are tons of games with this kind of plot.
But then I saw a video of someone going to a place that's actually like the Backrooms.
It's a shopping mall, but they found a blocked-off area.
People are walking around and it's bustling upstairs,
but for some reason, the floor directly below is blocked off.
So these people
found a passage to go down.
They went through the passage and opened a door,
and an abandoned shopping mall space appeared.
Knowing people are walking around right above them,
it feels kind of eerie.
Then they decided to go deeper.
They somehow found another gap and crawled through.
Once they came out of the gap, another new passage appeared.
Following the passage all the way,
they found offices with a ton of maps posted on the walls.
Of course, nobody was there.
Not stopping there, they looked for another door
and kept opening them and moving forward.
More endless spaces continuing...
Now they don't even know where they are.
They keep moving forward with a friend,
but the video ends with them saying they can't see an exit
and the maze just keeps going lol.
I don't know if it's real or not,
but it reminded me of the Backrooms, so it was intriguing and fun haha.
A top-liked comment from people who saw this:
This person is exactly the type to die first in a horror movie 💀
The end!
