Unless there is a history of incest in your past, there is no need to get freaked out! Incest in dreams, like sex, means you either need to come together on some level with your family member or it means you have recently come together on some level with the family member. It can also mean you need to take on a particular quality that family member possesses. Is your family member good with money? Is he or she in a happy marriage? What is it they have that you need or want to unite into your own life?
