The Smell of Death

Muhammad would wake up from a nightmare, sweaty and in a panic. When he try to sleep, when I'm falling asleep, suddenly my heart is so fast. What is the smell of death? I think fear. Muhammad can now spend most of a day tapping back and forth to talk with the guy in the next cell. But at night, when he can't sleep, he turns again to the concrete. And then again. And again.
