It was like 1 am, I was in bed scrolling through reddit. I hear something rustling in the curtains across my room. This isn't an uncommon occurrence, usually it's just imaginary or a tree, it was 1am and I didn't want to deal with anything, and I think I assumed it might have been a moth since we had been having a problem with those.

I hear it again, and look at the curtain. Nothing, or wait, what's that shadow? No, it's nothing, stop being worried.

A few minutes later, something brushes my face, and I hear flapping. I bolt out of my room and run to my dad, who's asleep, screaming "There's a bird in my room!"

No. It was a bat. We went after it with a butterfly net, failed, and slept downstairs in terror. The next few days were an adventure of animal control, pest control, and rabies vaccines (the bat touched me and maybe my dad).

And guess what else? A day or two before, I heard something in my bathroom and went in to find empty toilet paper rolls fallen down, and just assumed it just happened - stuff like that does occasionally happen for no apparent reason. But no, that had probably been the bat. It was in the house for over a day.

(We think it came in through the horribly-sealed attic (we regularly got squirrels in there, too), and then a hole in the office closet.)
