I had the worst zombie apocalypse lucid dream =/.
It was partially a SP dream, so every time a zombie would charge me I'd wake myself up. I couldn't move enough to shake myself out of the dream pattern, so it would just take up where it left off. I decided that the dream was symbolic of fear of the unknown or of death, so the next time I drifted to sleep I let the zombies catch me. It was not fun to be eaten, let me tell you.
