Gun
Handling a gun stands for a clear target and the will to act. Taking careful aim and firing is a good dream of getting what you want and pulling ahead of your rivals. Aiming but never firing marks a decision you keep postponing, and being shot was sometimes read the other way round in tradition, as a strong jolt or even as wealth. That said, this dream foretells no real accident or fight, and if the fear was strong, read it instead as a nudge to look at a relationship that weighs on you.
A gun goes only where it is pointed, so in a dream it shows plainly which way the mind is already facing. Old Korean dream lore had no guns, so the symbol carries straight over from drawing a bow and hitting the mark. What you are aiming at, and whether you fired or could not, is what separates the readings.
Readings by Situation
Taking careful aim and firing
A good dream of getting what you want and pulling ahead of your rivals. Old lore read striking the target as a hit and an achievement. It is a good time to make the decision you postponed.
Aiming but never firing
A sign of a decision you keep putting off. You have chosen where to aim but cannot pull the trigger, so write down what is holding you. Usually it is the fear of failing.
Being shot by a gun
Old books flipped this one over and read it as a hard jolt, or even as gain. Blood in particular they counted as money. If what stayed with you was the fear rather than the wound, look instead at whoever is leaning on you.
Having a gun taken from you or losing it
A scene painted by the sense that you have given up the lead. It does not foretell a real loss; it asks whether you are handing your decisions to someone else.
A gun appearing does not settle anything rough as bound to happen. Aiming is the core symbol, so read it as a picture of what you are currently setting as your target. If the fear stayed with you, look after your rest first.
