Lately, the thing that'll get me into this state is needing to pee. Then I have the dream where I'm looking for a bathroom but can't find one, or I can only find one that's exposed so that it's not private, and so I can't go. Eventually I realize that I'm having the pee dream, so I have to actively make the decision to either stay asleep because I need the sleep, or wake myself up because I need to pee.

Sometimes I can convince myself in the dream that I already successfully went. But then a moment later, I still have to go and the cycle repeats. At that point I decide I should wake myself up before I wet the bed (haven't wet the bed once yet, maybe that'll change when I get older?).
