To dream that you engage in a fight may reflect conflict in real life - with friends, family, or co-workers. Fighting could also symbolize an internal conflict, such as a moral dilemma - conscience battling against selfish desire, for example. There are other types of inner conflicts as well, such as tensions between opposing personality traits, such as your masculine and feminine sides, emotion and intellect.
Dreams involving fighting with someone close to you may reflect unresolved anger toward that person.
If, in your dream, you are unable to fight or feel weak - for example you try to punch or strike your opponent but you have no strength, it may reflect feelings of helplessness. Perhaps you lack confidence in your ability to overcome the conflict reflected in your dream.Related dream symbols
