Sleep never comes easy. My gear is under my bed when a missile comes our way. It happens every couple of weeks and we are the target.
There are mosquitos carrying malaria. There are camel spiders and scorpions everywhere. Must check my boots every time I put them on.
There are schnucks (army helicopters) carrying soldiers to and from the front line. Not all come back.
I have such vivid dreams that I actually see men coming into my room to get me.
I am terrified.
