Antlers often symbolize someone’s hardheadedness and stubbornness. Are you the one that is being hardheaded right now or is it someone around you? If the antlers in the dream are threatening or causing harm to you or anyone else in the dream, then your dream is trying to show you that this stubbornness is causing a problem in real life and it is time to either open your mind or – if it is someone else that is being stubborn – then move on from the situation.
Sometimes antlers can represent growth of the mind. Are you learning something new?
