When you're asleep, but you really have to go to the bathroom, so you dream that you get up and take a piss. But it only happened in your dream, see, so you still need to take a piss, and worse than that, you don't actually wake up, so you either keep dreaming that you're getting up over and over again to go to the bathroom, or you dream that you're doing something else, but you still need to take a piss, because you think you already went to the bathroom because you aren't aware it was just a dream.
And this happens to me with increasing frequency these days.
P.S. Why is it 50 degrees outside? It's MID-AUGUST and I'm sleeping with a fucking blanket. Okay then thanks bye.
