Doors represent both barriers and the idea of exploring potential. You may dream of a familiar house with a door leading to a room you didn't even know existed. Since the house represents your 'inner architecture,' the door can symbolize opportunities, unacknowledged potential or strengths that you are not considering. The door captures the idea of the way you hold yourself back from new experiences and also, the pathway to new experiences. The door can be a sexual symbol if this area of your life is currently being held back.
