I swear I saw a pair of glowing eyes behind you at 15:27. Rewatching to make sure I'm not losing my mind.

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??

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!

I legit heard a deep breathing sound at 9:10. Tell me it was just your mic acting up…

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

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

Did anyone else get a weird headache watching the part from 7:00 to 7:30??

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

13:06 - I saw a figure in the background for a split second… please tell me I'm not the only one.

If a ghost ever responds to you, just run. Don't even ask questions.

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

Am I tripping or did the walls look like they were moving slightly at 12:44?

When the screen glitched at 5:12, I got full-body chills. NOPE.

Can we appreciate that they KEPT GOING after hearing footsteps?? I would've been OUT.

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