nightmare

I'm outside in some unknown street, afternoon time and there seems to be a stadium behind me. Then out of the sudden I hear gun shots, and people started running. I dock a little and I'm a bit concerned because I don't see where the shooting is coming from. Then I see a car coming, my perception zooms and goes inside of it, there are about 5 coworkers from the school I use to work in. JO, a teacher is on the wheel, she steps on the gas as she comes near a curbside, near the side walk Im standing by. Apparently a gang, commanded by some french girls are shooting guns all over...
I manage to go away from the shooting and now I'm calmer, I'm sitting on a bench, trying to read an e-sign with red leters moving from right to left. Then a DC, male, appears on my right and shoots me on the torso. I fell in slow motion while feeling a strong jolt from the shot impact, that transitions to WL. Then I wake up.

It all begins outdoors, on the top of a mountain, semicovered with ice.. I'm observing a veteran is getting ready to go down a steep hill, a couple of hundred feet down. He's not even well covered, just wearing a t-shirt and black shorts, he's also barefoot!. He sits on the floor, starts scooting with hands and feet, and takes off!, he gains speed quickly, then he hits a bumpy curve and bounces up and down, and I think to myself "that must hurt". He's laughing and going all the way down.

Another DC appears and wants to do it as well...He is about 20 years old, he's well protected with gloves, jacket and padded pants, and has one of those go PRO cameras. He is going down the hill on his stomach?!... I only see when he takes off quickly.

Now I'm at the bottom of that steep big hill. There is a rectangular wooden box enclosed, where the two DCs ended up! I could see, and feel what is like inside the box. DC 1 and 2 are facing down, one after the other, and can't move much inside. Then I get that claustrophobic feeling! terrifying...!
the young DC is calling someone's name, but there isn't any answer. I glance outside the box and there seems to be a building... I go back inside the box, and I can't take that feeling anymore... I decide to tear the box apart so they could get out.!
