I had a wet dream in which I willingly relapsed

Your mind is giving you an excuse to give up. It literally made you utter the words "Two months is enough" and feeds you dopamine in your fantasies. Your mind is trying to trick you so it doesn't have to change.
Do not stop. Do not give in. That was in your dreams, and this is real.
Keep going.

 

I’ve had that same feeling of giving in and then complete regret and despair upon waking up. Then I realized it was just a dream and moved on. It’s not a reset or a relapse. Keep moving forward!

 

Don't get discouraged by it, I've had that same dream lots of times when I was beggining Nofap. In my case I just turned on the computer and fapped to some porn, so I didn't just dream with some sort of relapse: it was a plain and simple relapse, very vivid, exactly the same way as it could happen in real life (but it won't this time)
Take that dream as a promise that you are starting to recover. Nobody can know for sure what those dreams mean, but I know that they only happen after a long streak, so maybe they are one last, desperate attempt of our brains to try to get their old dopamine fix.
I just think of my brain as a spoiled kid who's been eating pasta, chips, and sweets for his whole life, and now that I try to feed him veggies he gets real bad tantrums, but once he realises that sweets and porn are never going back, he will have to substite those things with healthier food and hobbies and get his dopamine from other activities rather than porn. Our duty is to stand the tantrum until it finally gives in and eats its veggies.
