Creepy sounds
I noticed that if you are close to lava at the height where it could naturally spawn, it will trigger some kind of scary killer train sound. When I triggered this sound a bunch of times, it started triggering the new sound. It was like a monster growling and something being crushed at the end... It was longer and a lot scarier than a train sound. Did anyone experienced the same thing? Because I don't know how I'm gonna sleep tonight.
P.S. that's not creepypasta, this did happened.
