Ugh dogs and their barking

Last night I had a really weird dream. Maybe it's because I slept on my back instead of my side, which, I normally do, but my neck was really hurting. The dream had to do with me leaving a store with my dad (I think) and we were walking by this house when all of a sudden these policemen yelled something about a murderer. Then they yelled at us to "grab a gun!" and chucked them at us. I'd never shot a gun, but apparently I was supposed to help take down a murderer. The policeman, some chick, and I crouched down high up at the side of the house and aimed at some window or an opening or something weird like that. I guess someone, my dad(?) was going to ring the doorbell, then hide, and we'd shoot. Thinking about it now, I doubt the murderer would open the door, and he'd already be a step ahead, if he was good. But in the dream, right as we were getting ready to shoot, the other girl with the gun suddenly said her gun was locked or something, and at that moment I heard my dog barking. I figured my dog was in the front of the house with my dad and was gonna ruin everything and going to get killed, but before anything could happen, I woke up. Of course. Because my dog was barking. She was in my backyard with my dad, because he took her out when got up for work. Too bad I never figured out if I lived to kill the murderer. :P
