Fighting
Psychological (Freud)
Psychologically, fighting in a dream depicts an inner conflict: the wrestling between drive and prohibition, or repressed aggression that finds no outlet in waking life. The opponent often embodies a split-off, unloved part of one's own person.
Oriental reading
In the tradition of Ibn Sirin, a fight that ends in victory can announce triumph over an adversary or a hardship in life. A defeat, or a fight without blood, is often read as a call to patience and a sign of impending quarrel.

Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
