If you are running in your dream, in order to interpret you need to consider are you running away from someone or something, or are you just running like jogging. Normal running means you are the right road. If you have difficulty running it can mean helplessness, being held back by negative feelings, feeling rundown or out of steam.
Running away can be related to avoidance; issues of responsibility; guilt; new strength to avoid what is negative for you. If you are pursued see pursued.
Running toward some person or object may refer to ambitions or goals; willingness to undertake responsibility; a positive attitude. If a negative goal or situation it may refer to situations such as addictive or codependent ones, to which you are inevitably drawn even though the results may be disastrous. Has someone recently ran out on you?
