I can't remember much of what I dreamt last night, but whatever it was, it sort of took me back to my uni days of playing airsoft. Essentially, I was in an outdoor forested war zone, confined to a rather small area, typical of airsoft.
I had a pistol, AR, and sniper rifle, none of which I could name or recognise now.
The main difference from ordinary airsoft, however, was that the guns were deadly. The spirit of the game didn't change much though, as if we were just shooting BBs. So there wasn't really any pain, or sense of finality you have with death, even though people definitely did die. Eventually my team lost, but we were spared as a buddy and I sat against a pillar while the enemy horde carried on. It's not that we weren't spotted, but it's considered bad sportsmanship to shoot someone point blank.
