I dreamed that my mother-in-law gave me an old dress, put it on and liked it very much, and took off the dirty clothes. I'm not married, so I want to solve my dream of being the one.

This dream has two meanings. On the one hand, it means that you are getting married soon, getting married. On the other hand, because the dream is old clothes, it means that you will marry a second marriage or a man much older than you. If you don't really want to marry someone older than you, or don't like second marriage, you might as well have this dream, because there will be peach blossoms in the near future.
