If you haven't defeated a boss on a world there is a chance that they can spawn randomly. A message will appear warning you ahead of time.

That was a very long quasi-sentence.

I haven't heard of the Destroyer spawning on its own but I guess it would be possible based on the auto-spawning boss mechanics. It is something that happens in the game so it's not a bug or glitch. Now that you see it is happening, then it would be good to try to defeat them when you have a chance to prepare and summon them.

All mechanical bosses can spawn randomly before they are beaten, as long as the world is in hardmode

Eye of Cthulhu will spawn randomly when you have 200 or more health maximum

Both of these events have a warning several minutes ahead of time.

If you read "This is going to be a terrible night..." It means that it is a warning, also, did you defeat the Wall of Flesh?

"This is going to be a terrible night..." is for The Twins

I haven't even beaten the destroyer yet so idek whats going on and how can i stop it? i dont want to be carrying a platinum coin/s and randomly the twins spawns

Bosses will randomly spawn through out the days and such if in normal mode the beginner bosses will spawn (eow, king slime, eoc, boc and such) but if you are in Hardmode skeletron prime will spawn same with dow, spaz and caz will also spawn but they are rare if they spawn naturally
