I was scrolling on imgflip (In dream), and at some point I came across hentai or something, and the whole time it felt like I had to piss, but I obviously wasn't awake. I can vaguely remember the feeling of me moving in my sleep, then I felt the feeling of piss leaving me, then while I was in the dream, I thought to myself "Wait, did I just pee myself?", which woke me up instantly. So I felt around my sheets but felt nothing wet, then I realized what just happened, so I ran to the bathroom, and sure enough, it wasn't piss, it was splooge juice.
All of this happened barely even an hour after I went to sleep last night. It happened at around 12:58 AM.
