Peace be upon you. I had a wet dream (I saw things in a dream that cause desire and sometimes lead to ritual impurity) during Ramadan, but I'm not sure if it happened before or after Fajr. However, I assume it was after Fajr. When I woke up, I went back to sleep, and later when I woke up again, I performed the ritual bath after noon. Does this invalidate my fast? Also, does having a wet dream or dreaming about things that cause desire and sometimes ritual impurity multiple times during fasting invalidate the fast?
