i have dreams of going to the bathroom when i really need to pee but am too sleepy. i will dream of peeing so many times i get frustrated that the need to pee never goes away that i actually go to pee.
i watched Waking Life, it's about dreaming and philosophical ramblings, and it's from the makers of A Scanner Darkly, and there's one guy who tells this dreamer dude whos the main character that when he's dreaming he should turn the lights off and if the switch works then it's not a dream, but if it doesn't then he's dreaming and then he can like realize that in the dream and it'll become a lucid dream. and that's what i'm gonna teach myself to do, if i turn off lights randomly then it'll transfer into my dreams and i'll be able to lucid dream more easily.
