Dreamers Dictionary

Vision: Seeing a pistol: you have a bad conscience; animosity is brewing. Shooting a pistol: you are certain who your enemy is—but be more careful in the choice of your weapon! If you are pulling the trigger but the bullet is stuck in the barrel: you are defenseless and powerless in a very unpleasant situation.
