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

Anyone else hear that whisper at 8:42? Play it back at 0.5x speed… NOPE, I'M OUT.

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??

The way your light flickered just as that weird sound happened… classic horror movie setup. WHY DO YOU KEEP GOING??

If I learned anything from horror movies, it's that once you hear a whisper in a place like that… you should NOT answer back. Y'all just summoned something.

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

14:19 - did anyone else see that white mist move across the tunnel??

The way the camera blurred for a second at 5:40… like something passed in front of it. Freaky.

Rewatched that knocking sound at 12:00. It was three knocks. That's never a good sign.

Wait… what was that THING behind you at 4:17? It moved so fast!

Why did the camera shake at 3:45 like someone bumped into it… but you were both standing still?

Y'all ever hear of 'don't go towards the creepy noises'? No? Just me?

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?
