Arguments, quarrels and fights in dreams, are a manifestation of internal stress or issues we are currently dealing with.
This dream has an inverted interpretation. It signals family relationships and strong friendships in the future.
So if in your dream you had an argument with a family member or a friend you hold dear, you will be glad to find that things are going to get a lot better!
If you overheard an argument or a fight by others inside the dream, you have a concerning issue in real life which has not been adequately solved yet. This dream is also interpreted sometimes as a lack of resolve on your behalf.
Fighting someone "to the death" in dreams means that you will not be open-minded about necessary changes and or conversation about it.
