My Bladder Is Smart

and what i mean by that is i can be deep in sleep and my bladder will send a message to my brain that goes like this:

bladder: i'm full up
brain: really?
bladder: yup, we're out of space down here. better do something quick.
brain: no problem. i'll work with the subconscious to conjure a dream where the princess repeatedly has to use the bathroom, but she still feels like she has to go. it's guaranteed that she'll wake up, tinkle, and take the pressure off you.
bladder: sweet!
brain: yay, works every time.
