To dream that you are walking or moving backwards indicates that your current course of action may be counter-productive. Whatever you are looking for in life seems to be moving away from you. Thus, you may feel a sense of failure or belief that you are unable to achieve your goals and aspirations. On the other hand, moving backwards in your dream indicate that you need to back off or retreat from a situation that you are currently facing in your waking life.
Dreaming that you fall backwards suggests that you prevented yourself from making a bad decision or mistake. It may also mean that you are not ready to move forward and need to take a step back.
