So, is the counter for days without masturbation or just general orgasms?
Because the game sorta relies on you orgasming to progress so to see the wet dreams you're forced to essencially pause the game and spam sleep.
It counts all orgasms, however you get them. I made it that way because I don't want the scene to accidentally trigger during the course of normal gameplay, since most people are probably focused on advancing the story and not spending much time having Anon masturbate. If you want the scene to happen, you have to take deliberate action. Some people will see it by surprise while they're busy grinding through pizza deliveries and other errands, or during the early going when you can neither fuck nor masturbate (but still avoidable by taking Judith to the women's room). Either way, I don't want it to happen all the time or be inevitable unless you make Anon masturbate every
10 days to prevent it. It shouldn't be that hard to find other things to do besides having orgasms and, as you said, if you really want to trigger the dream without going through
10 days, just spam sleep until it happens. It should only take a minute.
You get a warning the day that it's going to happen, so save your game before you go to sleep so that you can try both endings. If you're into orgasm denial, play normally until you've seen them both!
