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??

Okay, but did anyone else notice the strange symbols on the wall at 10:15? Looked ancient… or cursed.

Wait, who was laughing at 7:51? Neither of you mentioned it, but I heard it CLEAR AS DAY.

This is the last thing I'm watching before bed… probably a mistake.

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

When you said 'Did you hear that?' at 10:05, my lights flickered. I am NOT okay.

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

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

Watching this with headphones was a mistake. That distant crying sound at 8:55??

15:47 - is that… a hand reaching from the darkness behind you? Someone confirm I'm not crazy.

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