If you are simply running with no goal, it may be an indication that you need to slow down in your every day life.
If you are competing, you need to consider your recent rivalries and realistically look at the current challenges.
If you are running in a race and win, your unconscious may be expressing confidence that you may or may not feel in the wakened state. Running in your dreams may also symbolize the energy levels, the strength, or the force that you have to get through life.
(A similar definition appears on top of the page for Race , since many people continue to ask me for running, I decided to list them separately.)
