Always dreaming that the door can't be closed, and you feel very scared, in fact, it shows that you are insecure inside, always worried about something, or afraid of loneliness. It's all in your heart. When you are always alone in the house, you will feel lonely, and then there will be an uneasy fear in your heart. Especially in the very quiet midnight, which is why you have been guessing and dreaming. Dreams are just expressions of this emotion.
The door in your dream represents your own sense of security. It may represent the door of your life or the door of your soul. Dreaming that the door can't be closed reflects that you are afraid that others will enter your own inner world, affect your life and learn your secrets.
