meaning of dreams bomb

 I have dream about being shot by a hand gun. the person that shot me is a police officer, who mad at me because i accidently left my bag at the post office and he pissed off because he had to wait for 5 hour for posting his mail. The post office employee thougth that the bag was a bomb, and the post office had to closed for 5 hour. The next day I went back to the post office and the post office employee remind me that wether I have forgatten my back pasck or not ??? And yes, I remember my bag. The person that shot me is just right behind me, and he overheard our confersation ( me and the clerk ) about my bag. Suddenly, the place of my dream have shifted to his (the person that shot me) house. All of a sudden, he mad at me because he had to wait for 5 hour because of me forgetting my backpack. He pull his hand gun and point it at me, so I run and he shot me a couple of time. I feel the sensation of being shot around my body and my leg. Some way some how I manage to run at a healthy person pace. I was thinking of running zig-zag to avoid his aim. After running a couple of houses, I looked back at his house and I saw he shot his own son in the head (until now, I dont know how do I know that the kid he shot is his son), and gave the kid a couple shot again. The kid was a teenager. After I saw that incident I run as fast as I could. He shot me while I'm running. I guest I manage to avoid the bullet, because there is no sensation of being shot like I felt previously. I was curious if the rampage has stop, so I circleling the house to see where he is. When I turn my head around I saw him with a hand gun on my face. I try to strugle by grabing his gun, trying to get his gun. Its not a big effort because it was a set up. He suddenly give it to me and suddenly he pull another gun that looked bigger than the one that i manage to snacth. He point the gun at me and he mumbling about how stressfull that 5 hour was. I try to run, thingking about running zig-zag again. I was begging for my life, then suddenly I woke up.
My heart was racing like hell.
