A research assistant experiences hallucinations while working in Antarctica.
"You hear a strange sound. It’s loud and insistent and returns again and again. You listen to it for a while before you realize it’s the sound of your own breathing and the moist rhythm of your heart. At night it ceases when you are no longer paying attention and the white steals into your 2 ½ x 1½ meter space in the housing unit. The room is barely larger than a coffin. Inside it, you could just as well be dead. You haven’t told Dr. Lubin. It’s just your heart falling quiet, leaving the job of keeping you alive to the white that surrounds you, infinitely greater than your tiny red. Who are you to deny it? After a while your heart starts up again, and that’s when you become aware that it had stopped."
