I had quite a disturbing dream last night and need some insight. ?

In this dream I arrived to a party on a field in a friends car. Once I got there a gang member came up to me and tried to take the car and I wouldn't let him. He told me to leave and I couldn't I had friends waiting for me and was going to hurt me but an old aquintance from school was there and told him to spare me, however they kept trying to take the car. My fianc�e was drunk and came up to defend me and threatened to hurt them if they didn't leave me alone. He pointed a fake gun at one of them when they threatened to hurt us. I took the car keys away which really aggravated the gang members who were sitting in the car while I was outside of the car. My close friend "Mina" was there and I told her what happened. She said that my fianc�e should be careful sticking up for me and the next thing I know I look over to a far corner of the field where my fianc�e is laying on the floor bloody with a medical examiner next to him...he is dead. I cry hysterically because I know who did it tho I didn't see it happen I grab him and cry with him in my arms as the medical examiner yells at me to leave him alone it's a crime scene lady!! Then I wake up, I assumed when I woke up that he was shot but in my dream I didn't hear gunshots nor did I see stab wounds on his body in the dream but he was very bloody. Please help decifer this dream I'm not exactly sure what it means.
