I am in the back of a helicopter with Barack, flying over the the waters of Cape Town. After a pleasant conversation, he slides open the door and I leap into the air. As I fall, I began to see the dark grey outlines of sharks swimming in the waters below. I am being dropped far from shore and I know I'll have to swim a long way back. More and more shadows appear and I splash down into the waters with the full knowledge that there are sharks everywhere around me. I am terrified. I tell myself it's only a dream.
