To dream that you are entering through a door indicates fresh opportunities that you will encounter. You are moving into a new chapter in your life and to a different level of consciousness. A door that opens to the outside represents your desire to be available to others more. A door that opens inward suggests your wish to have self-realization or internal discovery.
To dream about opened doors represents your ability to take on new thoughts and ways of doing things. To see light behind the door indicates that you are on the path to better spiritual faith.
To dream about locked doors indicates that you have either been denied chances or that you have missed them. If you are on the outside of a locked door, then you may possess some characteristics that others would call anti-social. If you are on the inside of a locked door, then you must accept the knowledge of a difficult lesson.
To dream that you are locking doors indicates that you are shutting yourself off from others. You have difficulty letting people get to know you and this is significant of a halt in development or maturity.
To dream of revolving doors indicates that your life is simply moving in circles and nothing is moving you forward. You could be sensing that your choices are going nowhere.
