Complete Dictionary of Dreams
by Dr. Mıchael LennoxThe rearview mirror may be featured in a dream when you are paying too much attention to your past and this is distracting your ability to move gracefully into the future.
A broken rearview mirror may indicate a moment when your ability to assess where you are going is inhibited in terms of learning the lessons of your past.
