What do you think this dream means?

Me, my fiancé, Nikki, and Brittany were sitting in her car listening to music. At Brittany's house, I was in the back seat talking to Nikki and my fiancé and Brittany were in the front talking. Nikki was smoking looking around and I asked her what she was doing she said trying to watch out for chris's UFO, and then a little toy space ship flies by. Chris's truck drives up and there's a bunch of stuff in the back including two arab men shirtless, wearing kakis pants and one of them wearing a head dress they grab long shot guns and direct my fiancé to get in the truck with Chris. Brittany is not in the front seat in fact she's nowhere to be found, i figured she must have hid somewhere. The two Arab terrorist get out of the back of the truck and one points the gun at me and Nikki and says "move I kill you". Nikki and I look at him he shoots Nikki in the head and then shots me in the head but I'm not dead yet I'm dying though. I turn to look at Nikki and her eyes are open with blood coming out of her head, she looks lifeless. The two men go in Brittany and Chris's camper to look for something. seeming to not notice I was still alive. My fiancé Justin calls the cops and tells them where we are and that I've been shot in the head. My head was bleeding and hurting all of a sudden I'm staring at what seems to be my lifeless body, and Nikki is right there staring at her lifeless body too. We Start praying and pleading with God to let us live that me and Nikki had kids that still needed us. I said "please god please let me and Nikki live we have kids that still need their mommies", "Dakota needs his mommy and daddy, and peran and auntie please let us live". And then a bright light comes shooting down.  I'm refusing to go and leave Justin and Dakota behind. I'm still pleading with God to let us live. Nikki is floating up to the sky but I stay behind.  When all this is happening I would occasionally look at Justin who was sad and kinda freaking out but didn't get out the truck
