war dream

my dream started with me laying down propped up in a corner of an old house, the roof was gone, looked like it was blasted away, anyways i look down at my feet and im dressed in army gear. then i realize that ive been shot, i was bleeding very bad from my stomach but it didnt hurt. i look up and theres 4 other soldiers holding an injured soldier, all of them were covered in blood. all i could hear was the injured soldier screaming from the pain he was in, i look to my left and theres another injured soldier laying in the other corner of the room holding his stomach, bleeding as bad as i was with the same injury as me too. he was just staring at me, i think he was dead, but i cant get that image of him stareing at me out of my head. i then look up at the sky and all i remember was seeing the sun then an explosion, everything in sight turned into a cloud and it went silent. i woke up after that and was sweating pretty bad. anyone have any interpretations of why i might have had a dream like this?
