My pupils can sometimes be odd, like, one is bigger than the other.
I often have an existential crisis. The reason I'm saying this is because nobody else I know seems to have them.
I just start to think really negatively. Like, "One day, I'll be dead. Forever. No more me." And other depressing stuff.
I have quite long arms, but I have short fingers

I love watching Batman movies, but that's the only superhero-ish person I like.
Whenever someone says something that a movie or book character once said, I'll just repeat that movie/book scene in my head and "lol" inwardly.
I dont usually have nightmares, but when I do, they're so bad that I wake up screaming, or I start muttering/wailing/talking in my sleep, or else I'll sleepwalk into the bathroom and curl up on the floor by the bath XD
I am secretly a singing and dancing kind of person, but nobody knows that except you guys :3
That's all I can think of.
