I had a dream that my brother was arguing with his wife. After a while he finally snapped and grabbed his gun. He saw me and my girlfriend and killed my girlfriend then shot me in the head. But I didn't die yet. I heard him shoot his wife 3 times then come back to shoot me in the head again but I woke up. What does this mean??

It means that you have been watching too many violent TV shows.
