Dream about being in a firefight?

I had a dream that I was in Iraq ( I was in Kuwait, about to go to Iraq when I had this dream) and I didnt have my weapon because I left it in my tent, and I was told to get another magazine of ammo. When I went to look for the Sergeant that had the ammo, I heard people saying the Iraqi's are coming, and they started coming over this hill that was right there. They started attacking us and I freaked out because I didnt have a weapon, so I low crawled into the nearest tent and told them what happened. I have had about 3 Iraqi dreams since I have been here that I remember (been here 10 months). Can anyone tell me what this might mean.
