Minecraft what does it mean when scary short music plays?

Question

I was in my super flat mincraft world breeding mooshrooms in the sunset then all of the sudden some scary short music plays... what does it mean? is herobrine coming? is someone pranking me? am i gonna get eaten alive? is something spawning?

Answer 1

No Herobrine isnt coming and nobody is pranking you its all ok its just the noise that happens when your in a ambience or ( a slightly darker area ) or its a dungeon. either way your fine. But if you see a random player and your the only one on your world and the random player has crazy white eyes then no your not fine.
