Biting someone in a dream portends that our aggression will create numerous enemies, or reveals the desire to possess and dominate the person we bite. If we are bitten it means that we feel hurt by the aggression of the person who bites us, or the aggressiveness of others if we do not recognize the person. It can also reveal the fear of sexual assault. If we are bitten by an animal the dream reflects the fear of letting ourselves be dominated by our instincts and passions, which will be symbolized by the animal that bites us.
