A woman asked the Messenger of Allah (way peace be upon him) about a woman who sees in her dream what a man sees in his dream (sexual dream). He (the Holy Prophet) said: If she experiences what a man experiences, she should take a bath.

سَأَلَتِ امْرَأَةٌ رَسُولَ اللَّهِ ﷺ عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ فِي مَنَامِهِ فَقَالَ إِذَا كَانَ مِنْهَا مَا يَكُونُ مِنَ الرَّجُلِ فَلْتَغْتَسِلْ

that Umm Sulaym asked the Messenger of Allah ﷺ about a woman if she had a wet dream like that of a man. He said, "If water is released then let her perform Ghusl."

أَنَّ أُمَّ سُلَيْمٍ سَأَلَتْ رَسُولَ اللَّهِ ﷺ عَنِ الْمَرْأَةِ تَرَى فِي مَنَامِهَا مَا يَرَى الرَّجُلُ قَالَ: «إِذَا أَنْزَلَتِ الْمَاءَ فَلْتَغْتَسِلْ۔»

"I asked the Messenger of Allah ﷺ about a woman who has a wet dream and he said: 'If she sees water, let her perform Ghusl.'"

سَأَلْتُ رَسُولَ اللَّهِ ﷺ عَنِ الْمَرْأَةِ تَحْتَلِمُ فِي مَنَامِهَا فَقَالَ إِذَا رَأَتِ الْمَاءَ فَلْتَغْتَسِلْ
