I'm not saying you need to like seeing it. Stop moving the goalposts. I never said it didn't matter to you or me / that you or I liked seeing that dream. You claimed it was NTR, which it is not. If there's a 30-minute sequence with the MC eating horse shit, I wouldn't enjoy watching / reading through that. But after the dream were over, I wouldn't somehow think the MC ate the dung in reality. In the sense of not enjoying that, it matters; in the sense of the MC as a character with a specific personality, etc., it doesn't matter at all. It literally does matter that it's a dream. That's the entire point.
Your argument is pretty silly. If you dream your wife cheats on you and then you wake up, does that mean she's actually cheated on you even though she's only ever had your dick since you got married? Using the same logic, if you dream you win the lottery, when you wake up you're owed money. Obviously not. NTR is when someone is cucked in reality, not because they fear it could happen or something made them have disturbing dreams.
I'm done with this discussion. If you don't like the game because of that scene, don't play. You're free to believe what you want, but I'm not going to debate this with you anymore.
