I heard that the teeth-falling-out dream means you grind your teeth in your sleep. I have them, too.
I also have dreams were my bed turns into a giant vat of cockroaches and other bugs, but that's because my little brother eats in my room and leaves crumbs in my bed
I'm afraid of the dark and heights, and am frightened by dead things if they surprise me or are falling apart. I can dissect a frog if I can make fun of it, but I'll never get used to the idea of kittens' heads sometimes falling off
Also, if I see something creepy at night it gives me a hard time falling asleep, like a spinning, laughing head or backwards-music.
