Nightmare Interpertation.

I had this nightmare about a month ago and it starts out Im with a group of people, I dont think I know any of them, and we are in the middle of a war. It seems to be in the future and we are in what looks like a huge valley full of greens. We arent fighting other people, we are fight these massive machines. As I look up I began to notice that everyone around me has died. I am now alone and am trying to find a way to survive. I jump into this lake full of muck and try to hide but one of the machines sees me and throws a nuclear bomb in the lake. I panic because I know Im about to die and I can see the fire spread over the lake onto the muck and I keep telling myself its almost over it will only hurt for a second.. and then I feel my entire body become engulfed with flames. The heat is so intense I can feel everything, and then I feel nothing. And I know I have died. I feel weightless and everything is black and numb. When I woke up I was sweating horribly and scared out of my mind. I really thought I was dead. And I havent been able to shake the intense feeling of death I felt in that dream.. can anyone help?
