Dreaming that the door of your home can't be closed: the door has many meanings in the dream, which generally symbolizes protection, because the door can keep others out. A door that can't be closed is usually a sign of frustration, such as always feeling that you have no privacy, or trying to end something, but you can't do it well. Your dreams may also be a sign of insecurity or stress.
Your background is the key to dream interpretation. If you think about it, you may be able to solve your dream. Good luck!
