You have to pick:

Everything looks like its from the set of a horror movie about an evil circus

Everyone talks like an evil gnome and all sounds sound like they went through a creepy, evil echo filter

What do you mean creepy?
does everything you hear sound like terrifyingly creepy?
or is it just some things in particular?

Everything.

If everything sounded creepy, you'd get used to it, and it would no longer sound creepy.
