This is of the nocturnal kind.
I had one this morning. I don't recall the events before this part of the dream or if it just started randomly. But I was in a high school girls' bathroom. And the stalls were pretty much open. Well, in the beginning of the dream the stalls had side walls but the stalls were pretty big and wide and the 'door' wasn't very big so really you could see in quite clearly. I think as my dream went on the walls shrank even more. Anyway, there I was doing my business and these boys were coming into the bathroom. Of course, this is a rather uncomfortable situation. (And the bathroom was extremely large, like a small cafeteria size.) It gets busier in there with more people and boys coming in there. I think at this point the bathroom was pretty much like a lobby kind of area - where some people walk through to leave but others were hanging about. Now I'm getting really bothered and at some point I'm starting to yell at the boys to get out. Bad enough to be sitting there but I needed to wipe and I really didn't want THAT being observed! Now the last party is fuzzy because I was starting to wake up but I think I ended up trying to pull my clothes up as discreetly as possible while trying to come up from a sitting position and not give everyone the full monty below the waist.
I have some seriously weird and disturbing dreams!
