What is the most horrifying creature scream/noise you've ever heard?

[Lego lad]

Parasaurolophus horns https://www.youtube.com/watch?v=lBU6zfI1b0U

they used the horns on their heads to blow air out and make weird calls, might be outdated tho

Got some more:
Chozo Ghosts
Kraid
Headcrab Zombies
Godzilla
Babadook

also if you're going to put a sound try to provide a link
if you can't, that's fine, but make the effort so the rest of us can share the experience

Real-life: Dogs barking at me.

Fictional: Lavos Scream.

For me it would be

Fiction Choice: The hunter pounce sounds (WARNING: Loud) from left 4 dead would be pretty terrifying in real life.

i think actually getting pounced on OwO whats this? would be more terrifying
