War
War in a dream is collision on every side, so it stands for large conflict and competition. Traditional reading took winning the fight as a good omen of getting ahead of rivals, and gaining a weapon as authority and drive arriving. Being chased and hiding, by contrast, signals something you are avoiding, while the war ending means a long-running dispute is settling. It does not forecast real conflict; most often it is a scene drawn by a standoff in your own mind.
A war dream holds a conflict that only ends when one side wins. Traditional reading separated the meanings by who won, and read winning favourably. Who was set against whom, and whether you stood inside it, is what divides the reading.
Readings by Situation
Winning the fight
A good omen of getting ahead of rivals. Tradition read winning as things going the way you intend. With a contest ahead, this reads well.
Gaining a weapon
What decides this scene is that the thing in your hand is a weapon. Tradition read gaining arms as taking up a post, and a weapon changes how the other side behaves simply by being carried, without ever being used.
Being chased and hiding
What marks this scene is that you never see the face of whoever is chasing. In a war dream being chased reads less as one particular person than as being pushed by the whole situation.
The war ending
A good omen that a long-running dispute settles. Tradition read fighting ceasing as reconciliation. If a tie has gone distant, read it as the time it eases.
A war dream does not forecast real conflict or a real quarrel. It is a scene drawn by what you are up against inside. Picking a fight on the strength of it is not advised.
