Is it normal that i hate leaving the blinds open at night?

This is normal. Back in my teens I made the mistake of not closing the blinds and a perv from the woods was watching me. My dog at the time, Blackie, chased him away. She came back with one of his shoes in her mouth.

I fant shut them it creeps me out when they are shut

I guess it depends where you live? In the city you probably should close your blinds

Only at night? Mine are closed at all times.

Don't blame you.
