Does observing some forbidden things and subsequently having a wet dream during the daytime in Ramadan invalidate the fast?

Watching forbidden things is prohibited, whether in Ramadan or at other times. However, it is more severely prohibited in Ramadan due to the violation of its sanctity and its contradiction to the purpose of fasting (which is piety). The perpetrator must engage in sincere repentance by refraining from it, feeling remorse, and resolving not to return to it. Wet dreams during sleep do not affect the validity of the fast, due to the absence of intention and the lifting of responsibility from a sleeping person.
