Break In

I was home alone in the apartment I grew up in and thought I heard the front door being messed with. I went and made sure it was locked before returning to whatever I was doing. I came back later to find it slid open like a patio door, even though it was a regular door, and a woman standing outside my apartment. Feeling confident, I freaked out and demanded to know what the hell she was doing trying to break into my house. She said something about a kid left a doll up here, but I knew that was a lie. Then a man forced his way in and began looking around my house and messing up everything. I had a knife from the kitchen and ran up and stabbed him right where his heart should have been, but he didn't even flinch. He simply said something to the effect of "that hurts" and kept poking around my house. At a loss, I tried to shoot him in my mother's bedroom with Jimmy's gun, but it wasn't even loaded. I went to look for my gun, and another guy found his way into my home. This one was a white guy with semi long blond hair and a southern accent (the other guy was a black man in a white tank top). I tried to shoot him with my gun, but it didn't seem to affect him, and when I shot him with my father in law's gun, he just looked at me like I was stupid. The gun didn't even make a loud shooting sound, just a sort of whoosh sound.
