The Big Dictionary of Dreams

by Martha Clarke
In an oneiric situation this image is always a sign of conflict. Its interpretation depends on the place the dreamer is placed within the scene: whether she is an observer, a participant, whether she wins or loses, or walks alone over the battlefield. The stage where the fight takes place is associated with the environment of the dreamer in real life. Moreover, you must address the feelings of triumph or defeat to understand the message of the unconscious.

Complete Dictionary of Dreams

by Dr. Mıchael Lennox
There is a distinction between war and battle. War implies an ongoing state of flux, whereas battle is the actual shift taking place in a small increment of upheaval and change as part of an ongoing period of transformation.

If you dream of being in a battle, look to where in life your defenses might be running on high. Also consider where changes in boundaries are imminent, both in your outside world as well as within, as many battles are with yourself.

Dream Symbols and Analysis

A dream in which you see or participate in a battle is a sign that you are working too hard. You should take some time off. It’s also an indication of a clash between your levelheaded thoughts and impetuous acts.

The battle can also indicate sexuality, and that you are too aroused or might be restraining your desires.
