What is the ruling on marrying a girl despite the mother's strong opposition to it, and her considering this marriage an act of disobedience due to dreams the mother had? And what is the correct course of action in this situation?

The questioner's mother objected to his marriage to a woman for flimsy reasons that do not necessitate obedience, such as her superstitious belief due to the death of cats. The questioner has married, and he must now satisfy his mother and show her filial piety, because the mother's right is immense.
