Dream About Coworker Shooting Boss Boyfriend Faking Death And Being Shot From Behind

I was working in this car shop and I was in the garage with a coworker and our boss when we started hearing a loud banging on the back door in the room next door so my boss went to check on it. My coworker and I were confused but kept talking about whatever we were talking about thinking someone got locked out by accident. Then we heard a couple gunshots. The coworker that was banging on the back door shot our boss and then my boyfriend when he had gone to check about the first gunshot. Then he came in aiming the gun at my coworker and I and he said something about how he didn't want to hurt us but we needed to cooperate. So he lead us to this other room that had a bunch of tables and sat us down while him and his "goons" patrolled the room and rest of the building. I was distraught because my boyfriend was dead. My bosses wide was there too and she was really upset and drinking a bottle of wine. I asked if I could have some and took it to my table to cry and drink. The coworker/shooter came over to the table I was at and asked if I wanted anything and I asked if I could go see my boyfriend/say goodbye and he said that was fine so a friend grabbed my hand and ran me to the room that had his casket. As soon as I opened the casket I realized he wasnt dead, just faking and I started crying happy tears. Then seconds later I was shot from behind by someone in the back of the room but it was too dark to see if it was the coworker/shooter or a goon and I fell back onto the casket with my boyfriend and died.
