I dreamed that the big black bear at home was going to rush in and bite me.

A repressed dream. The black bear in the dream symbolizes stress. The external pressure is just like you. Father and sister are part of your personality, and the house represents your heart. You are resisting this pressure by pushing the door together. But it failed.

So you changed from resistance to change, and part of your personality successfully escaped (sister ran away). The part of personality that symbolizes dignity (father) has not been saved. In other words, some kind of external pressure makes you confused. There is a man still alive in the family photo, which means that a personality is still alive. If you are alive, you still have ideas.
