When you dream elevator means: A powerful symbol, an elevator can suggest either a positive meaning or a negative one. The symbol of progress or higher consciousness is represented by going up, while the subconscious side represents the dreamstuff. The association of elevators with buildings implies that they belong as part and parcel of the dreamer’s inner world. If the elevator reacts in a strange way, such as getting stuck or crashing, it could indicate a problem with these areas.
