The first people in your life with whom you have any social interaction are the members of your family. Therefore, a dream about a family member can represent any waking life social situation.
For example, if you are arguing with your mother or father in a dream, you may be having a problem with another authority figure, such as an employer, in your waking life.
If you dream that an older sibling is teaching you how to do something, you may be hoping that you will receive assistance with something from someone else in your waking life.
A family in a dream can also represent security and community.
The meaning of a dream about family will largely depend upon your personal experiences with your own family members.
