Rulings Regarding wet dreams for women

I have a few things I’m unsure about regarding ghusl after sexual dreams: 1. If a woman wakes up from sleep without remembering that she had a sexual dream, and only recalls it hours, days, or even a week later after praying, and did not check for any wetness when she woke because she did not know about the dream at the time, is she required to redo her prayers or perform ghusl? 2. I have discharge that varies with my cycle, sometimes very light or dry, but heavier during ovulation. If I have a sexual dream at that time, I cannot tell whether any wetness upon waking is from the dream or my normal discharge. In this case, is ghusl required, or only if the wetness exceeds my usual discharge? 3. I’m also confused and don’t know what exactly counts as a wet dream. If I have a sexual dream, does it have to include climax, or do I still need to check even if there was no climax in my dream? I’ve seen different things online and want to know what actually requires ghusl. 4. Is ghusl required if there’s only madhi after a wet dream, and what if I can’t differentiate?
