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??

This video unlocked a deep primal fear I didn't know I had. Thanks, I guess??

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

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??

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

Imagine watching this and suddenly hearing the same whisper IRL. Nope, I'm out.

7:13 - why did the audio cut out for a second? Almost like something didn't want to be heard…

No one's talking about the weird whisper at 9:33… did you even hear it while recording?

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

At 6:59, it looks like something tugs on your backpack. Please check that footage again!

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?

Why did my phone volume change by itself when you heard the static at 11:10? I'm actually scared.

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