What is the interpretation of a young man's dream in which he sees his beloved, who is older than him, and sees a woman and a child urinating on a wall, and sees himself kissing her breast which then becomes covered with hair, and is his marriage to her contrary to Sharia, customs, and traditions?

A man marrying a woman older than him is permissible. The Prophet, peace and blessings be upon him, married Khadijah, may Allah be pleased with her, and she was older than him. Also, Usamah ibn Zayd married Fatimah bint Qays, and she was older than him. If the one opposing the marriage is a parent, then obedience to them is obligatory, unless the son fears falling into sin by not marrying her.
