Lucid Dreaming

I had a dream the other night where, I was at this ski place with my girlfirend, and we were using the ski lift thing, but they had no backs to them just a place to sit. Well these dumbass's in front of us were fucking around and this kid pulled out a gun and was like "it's not loaded" and he pulled the trigger, killing his friend. then he was like "what the fuck?" and pulled it again, But this time it hit a pole, bounced off the pole and hit my girlfriend in her chest( her name is Brittany) But I didn't know it hit her in the chest, I looked over and she was like trying to gasp for air, and her eyes were all big, she was falling back, and I was trying to hold her up but I couldn't. So I fell with her and hit the snow. I didn't know what the fuck was going on cause it happened so quick, but I lifted up her shirt cause she was holding her chest, and I saw that she had been shot right in the center of ther chest. Next thing I just appeared at my house on my kitchen floor and she was in my arms, she was breathing slower and slower then I felt her body turn cold....she died! My Grandma called the police, they sent someone to get the body, this guy came and was like, here cut out her tounge, I'm like fuck you I'm not doing that, and he was like well you gotta take something, want a finger or a toe, I'm like dude just fuckin get the body out of here.
Then he grabbed me and was like "JUST TAKE SOMETHING" I punched him in the face and ran down the street. Then I woke up it was horrible.
