To dream that you are in a fight indicates inner turmoil. Some aspect of yourself is in conflict with another aspect of yourself.

Perhaps an unresolved or unacknowledged part is fighting for its right to be heard.

It may also parallel a fight or struggle that you are going through in your waking life.

If you are fighting to the death, then it refers to your refusal to acknowledge some waking conflict or inner turmoil. You are unwilling to change your old attitudes and habits.

To see others fighting in your dream suggests that you are unwilling to acknowledge your own problems and turmoil. You are not taking any responsibility or initiative in trying to resolve issues in your waking life.

To dream that you are trying to fight, but cannot throw your arms as hard as you want signifies lack of self-esteem and self-confidence in some area of your waking life. You are unsure of your next move.

This dream may also reflect your actual state of REM paralysis during the dream state.
