'A'isha the wife of the Messenger (ﷺ) narrated:

Umm Sulaim, the mother of Bani Abu Talha, came to the Messenger of Allah (ﷺ), and a hadith (like that) narrated by Hisham was narrated but for these words. A'isha said: I expressed disapproval to her, saying: Does a woman see a sexual dream?

وَحَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ، حَدَّثَنِي أَبِي، عَنْ جَدِّي، حَدَّثَنِي عُقَيْلُ بْنُ خَالِدٍ، عَنِ ابْنِ شِهَابٍ، أَنَّهُ قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم أَخْبَرَتْهُ أَنَّ أُمَّ سُلَيْمٍ أُمَّ بَنِي أَبِي طَلْحَةَ دَخَلَتْ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ بِمَعْنَى حَدِيثِ هِشَامٍ غَيْرَ أَنَّ فِيهِ قَالَ قَالَتْ عَائِشَةُ فَقُلْتُ لَهَا أُفٍّ لَكِ أَتَرَى الْمَرْأَةُ ذَلِكِ

The Prophet (ﷺ) was a teacher for his nation. He used to teach it all the etiquette of intercourse and purity. In this hadith, Aisha, the Mother of the Believers, narrated that a woman (Umm Sulaim as Anas ibn Malek narrated in Sahih Muslim) asked the Prophet (ﷺ) if it was obligatory upon a woman to bathe if having a wet dream and seeing semen. He answered, “Yes.” He welcomed her question while Aisha expressed her refusal of that type of question. He saw that it was an important religious matter that a person had to inquire about. In Abu Daoud’s narration, he said, “Women are counterparts of men,” which meant that Islam addressed them with the same legislation as men. Out of his modesty, he implicitly indicated that both genders may have had a wet dream. He thought that the woman understood what he meant through his concise answer. He clarified that the kid resembled his maternal or paternal uncles based on which semen (father’s or mother’s) preceded the other, which was subject to Allah’s will. Finally, this hadith contains the following benefits: (1) It clarifies how the Prophet (ﷺ) took much care of teaching women the rules of Islam, and (2) It confirms that it is permissible for women to directly ask scholars..
