I dreamed that my parents and I were standing in front of the mirror, which seemed very harmonious. My brother has to walk around from time to time.

According to Duke Zhou's explanation, your brother is hostile to you to some extent. You have a lot of good things that will be destroyed by your brother. Your brother will affect your relationship with your parents. There are good and bad.

In fact, many times, don't be too superstitious. Dreaming is actually a speculation based on what people think during the day. I advise you not to believe it too much. But pay attention to your relationship with your parents and brothers. Parents and brothers have only this life and no afterlife. Even if there is an afterlife, who knows that dealing with this life is a perfect life? So I advise you not to think too much. This is just a dream.
