Would monsters suffer from the same social, mental/neurological, phobias, and developmental problems that humans do?
Like would there be ADHD vampires?
Down syndrome werewolves?
Mummy's with anxiety attacks?
Zombies with social anxiety disorder?
A Loch Ness monster that was afraid or the dark?
Or any combination of such things.
I'm not sure if that would make them less or more terrifying honestly.

And yes it's stupid but it was something I was wondering. A new spin on monsters IMO.
