A non-fiction account.
It's impossible to communicate the nature of physical exhaustion to those who have not experienced it. There were three of us, but the other two are dead today. We sat a river no more than two inches deep in the middle of a fetid swamp, eating small water snakes which were squirming in the mud by the hundreds and washing them down with water from our canteens.
We had not eaten or slept for four days. We were in a state of starvation-enhanced exhaustion that caused us to have vivid dreams that we experienced while wide-awake. T. E. Lawrence said, “all men dream but not equally” however in that place, at that time, we all dreamed of home.
