Are you the ballerina in your dream? If so, you are indicating a very graceful heart and the ability to find self-discipline in order to conquer a situation in your life you are anticipating with reticence.
Dreaming of watching a ballerina indicates that you are seeing a graceful aspect of yourself that you are as yet unaware you possess. Your life is going according to plan so relax and make changes gently as you see fit.
Dreaming that you are unable to stop dancing indicates that you may work too hard and expect too much of yourself at times.
