From the movie The Sacrament:
Well, it's officially 5:00. So much for the greatest night's sleep of our lives. Tried to go to sleep about an hour ago. Whatever they're doing in the pavilion seems to have stopped, so it's finally quiet. Ugh. Neither of us could sleep. It's a weird night. Looks like it's finally getting to us. Well, I'm actually really scared. It's the most scared I've been in a long time. Ready to go home.
There are two problems I have in this excerpt. First of all, what does it's finally getting to us mean exactly? Is he talking about the weird night that's finally getting to them, like, it's starting to give them a hard time?
And my second question is about the grammar of the second sentence in a bold font. What he's saying there means it's the instance where he has been scared the most in his life and that he hasn't been so scared in a long time? Is that a correct understanding?
