Dream About Home Invasion And Loss Of Mother

I dreamt that someone broke into my house, trying to kill my mother. My Dad my brother and my Mom were home and I too. But while we were chilling some people came into our house, trying to kill my mother. I killed most of them thinking my Dad and Brother were fighting back. I killed most of the people there but when I got into the living room there were only my dad and my brother, laying and looking at their phone. When I asked where mom was they told me chilling that she was dead. I was sooo scared, heartbroken. I started crying.
