The door is dreams usually represents the way from one part of your life to another. If you see yourself opening the revolving door and walking through them, it means you are feeling very assured about your actions and appearances among the others. If you are unable to open the revolving door or are afraid to walk through them, you are lacking the self-confidence and trust. Perhaps the dream suggests to cope with yourself and be more confident, because you always need to believe in yourself no matter what situation you are in.
