Is ghusl obligatory for someone who felt the sensation of a wet dream and was too lazy to check, and saw nothing upon waking, knowing the abundance of usual discharges and the habitual doubt about them?

If a woman sees in her sleep that which excites lust but does not see semen, then ghusl (definition) is not obligatory for her. This is because the obligation of ghusl is contingent upon seeing semen, based on the Prophet's (peace be upon him) saying: "If she sees water, ghusl becomes obligatory." And based on the statement of Umm Salamah: Umm Sulaym came to the Messenger of Allah (peace be upon him) and said: "O Messenger of Allah, indeed Allah is not shy of the truth. Is ghusl obligatory for a woman if she has a wet dream?" The Prophet (peace be upon him) said: "If she sees water." The scholars have unanimously agreed that if one has a wet dream but does not find semen, ghusl is not obligatory upon him. And if one finds semen but does not recall a wet dream, ghusl is obligatory upon him.
