It is all those dumb ass southerners intent on revenge for your insults...
Interesting dream, I don't recall ever smelling anything good or bad in a dream and I have dreamed of situations with great potential for good and/or bad smells.
I have often dreamed of guns but I have never fired a gun in a dream. When I try to fire a gun it morphs and I can't get to the trigger. I have dreamed of fighting and I have no difficulty in beating the shit out of my dream opponents but for some weird reason I can't shoot anyone.
