If you dream about your family, it may be a way for your mind to express feelings and concerns about your real faimly that you could not express in daily life.
Some believe that this dream usually has nothing to do with your actual family members, but rather the male and female sides of your own personality or self.
So in a dream, your father may represent your expressive and protective aspects, while your mother could stand for your receptive and nurturing side.
If family members behave very differently in a dream than they do in real life, or if unexpected things happen when you are with your dream family, the dream is probably a way of releasing your anxiety about real-life family issues.
For instance, if you dream of a family member trying to hurt or kill you, it reflects a real-life concern about this person.
They are acting in a way that hurts you, or threatens your emotional happiness.
