I read now a little here. Personally I don't like dream scenes. They're mostly a easy/low effort way for devs to show something, that isn't ready for the main story or will otherwise never happen. As for the choices you gonna implement, I appreciate something like this very much! It gives the player the chance to customize and control their experience with your story. Regarding the pregnancy content, I would like to see midgame content of it, but pregnancy is one of the main kinks I look for. Way to few in my opinion good games feature it. But if you don't like certain contents, like pregnancy, I suggest to skip it. You might not enjoy creating it and probably won't meet the expectations of the fans of these kinks. What I don't like, is forcing (a) certain (controversial) kink(s) on the player, that's what choices are for.
Keep in mind, this is only my opinion, based on my experience with the AVNs, that I played and based on the few interactions I had with a few of the devs. Nobody is obligated to have the same opinion or to follow my suggestions.
