A dream involving your back symbolizes your strength, inner feelings or outlook.
If you are feeling pressured or stressed in some part of your life then you may experience back pain in a dream. You can also experience back pain if you are having financial or support issues, or if you have an underlying back problem.
To observe someone's back in a dream could suggest that something unexpected and unwelcome may occur in your life.
To turn your back away in the dream suggests that you are hiding your feelings in some way or turning your back on something or someone.
