What do you imagine when you think about the desert? A wide, dry wasteland with sand wherever you look. No shade to hide under and no water. The sun high up in the sky, burning down on you while you wipe the salty sweat out of your face. You walk in a straight line for hours in search of a good place to set up camp. The hallucinations continue, and you realize your mind is playing games. The desert is not flat and dry.
