This is the kind of video that makes me triple-check my locks before bed. Y'all are brave (or crazy)!

Props to you guys for going that deep underground, but I gotta ask… who was filming from behind when you were both in the frame??

At this point, I don't know if I'm watching a horror doc or a found footage movie. Either way… SUBSCRIBED!

When you turned the camera at 11:42, I swear I saw something peeking from the corner. Chills.

Nobody is talking about that low growl at 16:55… HELLO?

Every horror movie starts with people doing exactly what you just did…

How do y'all sleep at night after filming this??

You should NOT have touched that old wooden door at 14:45. That's how horror games start.

Dude, when you turned that corner at 15:20, my heart literally stopped. Too eerie!

Not even joking, my dog started growling at the screen around 10:50. What did you guys awaken?

9:01 - That was NOT an echo. That was a second voice. Who else heard it?

I paused the video at 4:21 and I swear I see something peeking from behind that doorway. Nope nope nope!
