Dreams dictionary: Shotgun
Dreams dictionary: Interpretation 1
To see or shoot a shotgun in your dream means that you need to better focus your energies toward your goal.
Dreams dictionary: Miller Dream Interpretation
To dream of a shotgun, foretells domestic troubles and worry with children and servants. To shoot both barrels of a double-barreled shotgun, foretells that you will meet such exasperating and unfeeling attention in your private and public life that suave manners giving way under the strain and your righteous wrath will be justifiable. See Pistol, Revolver.
