weird, i had one a few weeks ago where i partially cut through the shaft behind the head with a cigar cutter. i threw a band aid on it and then acted like shit was normal for the rest of the dream.
if i'm depressed/upset, i tend to have zombie dreams. one had me dilapidated house that was full of zombie animals, i remember a zombie horse chasing me around and then the dream ending with me being trapped in a car with a zombie squirrel. worse than that was a different dream i remember where it was just me in a neighborhood full of zombies, guns laying all over the ground like it was a video game, not a single one had ammo. the entire dream was me running, picking up and trying empty weapons till i was cornered in a basement and then chewed on.
if i'm not happy about dental stuff, like a cavity, i dream of all my teeth falling out.
i never have a "normal" dream and i'm not one who can control the situation.
