It does, but that's only like five minutes tops.

That movie certainly felt horror at times. Was really well done

Not much weirder than Bird Box. In it, you receive an immediate urge to kill yourself from seeing the monster. Something like this would work just as well for hearing it. Some have already mentioned sirens in this thread, which also fit well.

Could be something Lovecraftian. Whispers in the dark that are always there, but only detectable by a select few until yadda yadda. Event Horizon comes to mind.
