Dreams of a Twelve Step Program represent a light at the end of the tunnel. You are coming to believe in a higher power, and becoming willing to turn your life and will over to the care of your higher power in order to get you through this drastic and powerful time of change. You are becoming honest about what is no longer working for you, and willing to take responsibility for your life.
If you have not yet started on this path, this dream may be a sign for you to begin. See Breakdown/ Breakthrough Dreams.... Strangest Dream Explanations
