I got a call this morning from my new employer informing me that I've passed my background and medical tests and that I'll be starting on April 4th, as expected. Sweet! I can't wait to get back to work, and I think I'm really going to enjoy this new job.
I had a dream last night that I was at home alone in a huge mansion and that bandits were after me. All I had was a .38 revolver (with a 12 round capacity, somehow) and I went around shooting them. It was pretty sweet. But there was one bandit that I couldn't kill, no matter how many times I shot him in the head. Each time I shot him he got stupider and stupider, but he kept coming after me like a zombie. When the sun came up (in the dream) other people came into the mansion -- including a dun dealer who kept selling me more ammunition. I tried to get other people to help me with the zombie, but they just laughed. Half the bullets the dealer sold me were duds, and he thought it was hilarious! The people said, well, he isn't hurting anyone else, just you, so why should we get involved? Other people said I should "pull his feeding tube". It was all very frustrating, yet amusing in hindsight.
In dreams, 12 is commonly interpreted as representing spiritual strength or divine perfection. Mansions usually represent your pinacle of growth, or perfection of yourself. Thieves or bandits are the forces that want to take what you have from you, and probably aren't literal people (unless you recognized them.)
My armchair analysis? You feel like everything is going right, physically and spiritually, but there is one issue that you can't seem to deal with. You've tried to shore up what you see as your own spiritual failure with religion (the gun dealer), but it only lets you push the issue away, not deal with it. I think this is an issue that society is general runs from (the apathy of everyone else) but you feel the need to confront it.
Taking a calculated guess, your own mortality is a good guess (with the veiled Schaivo reference as a pointer to it.)
Congrats on your job. Now go do the work of the incredulous genius and create for the good of all mankind.
