I wonder what your family atmosphere is like in reality. There are three kinds of guesses for reference only.
First, your family seems peaceful. Everyone is considerate of others and seldom gets angry. If so, some common and inevitable negative emotions, such as anger, injustice, sadness, etc. It is likely to be suppressed, and these energies will not disappear naturally without treatment. If you suppress it in your dream, it may turn into a flood, dragon.
Hurricanes, wars, etc.
Another guess is that everyone in your family is very independent, and there are few opportunities for in-depth communication together, so your dream has created some disastrous scenes. In this case, the whole family will closely unite, rely on each other and support each other, and the distance between hearts will be much closer.
Another is that there are some potential contradictions and conflicts between you and your family, but in reality you will think too much about what you should or must do, so this impulse will be shown in your dreams. At the same time, if you take too drastic measures, you will not only hurt others, but also hurt yourself. If we adopt some more effective methods, we may achieve good results.
