I dreamed that my brother and sister said that I didn't give my mother money.

According to some western dream interpretation theories, the younger brother and sister in the dream usually represent a part of your heart, which may be your child's self and innocence. The dream mother symbolizes love and responsibility. In this dream, my brother and sister said that you didn't give money to your mother, which may represent your inner anxiety and guilt.

This dream may remind you that in real life, your sense of responsibility to your family or mother is not strong enough, or you feel guilty and feel that you have not fulfilled your due obligations and responsibilities. It is also possible that you are worried about your financial situation or financial problems and that you can't give your family enough financial support.

However, please remember that this is only based on some western dream interpretation theories, and the interpretation of dream interpretation is not scientific and inconclusive. Everyone's dreams may have different meanings and explanations. So the above is only a possible explanation, and it needs to be analyzed according to your personal situation and life background.
