I still do it once in a blue moon.
I used to have lots of dreams in which I felt the need to relieve my bladder. One of two things happened:
1) Most of the time, the dream kept finding excuses so I couldn't use a toilet. For example, there wasn't one anywhere in sight, or there was, but there were people in there (usually including my parents) chatting enthusiastically who wouldn't leave so I could have some privacy. Once, I dreamed I was on a school trip, in a hotel, and the toilet had a door with a completely transparent glass pane, and there was a large corridor on the other side bustling with people walking all the time, so I waited and waited like an idiot for them to leave the place empty, which didn't happen before I woke up.
2) A few times, I managed to reach a secluded toilet (usually a big room full of fancy toilets coming in all shapes and colors), and even saw my urine stream, but, no matter how much I peed and peed, I never got any relief. I eventually got bored and resigned myself to my frustration.
This is how I learned that, when I pee in my dreams and do feel relieved, I've just drenched my bed. It's only happened two or three times so far, but I recognize it immediately and wake up to find I've actually wetted my bed
