The unnamed two guys in 2017 became interested in anomalous places and went to travel around their state of Massachusetts, visiting unusual sights.
One had a GoPro camera with him, which he fixed on his head as they entered an old railway tunnel in the west of the state (Paranormal News - paranormal-news.ru).
The official name of this tunnel is Hoosac Tunnel, and the unofficial name is "The Bloody Pit", because during its construction at the end of the 19th century 196 workers died here for various reasons.
The tunnel stretches for an impressive 5 miles (one of the longest tunnels in North America), so it is not surprising that the video filmed in it is blacker than night, the guys only had weak flashlights with them. However, the sounds in this video are quite good. Including a low, disembodied female voice that said “You're gonna die” while the guys were inside the tunnel.
Except for the two of them, there was no one here, both are sure of that. In addition, they as best they could, examined everything there with lanterns and did not find anyone.
This tunnel has long been known to the locals as a haven for ghosts.
