Somewhere in the middle of the ocean sperm whales sleep. They sleep upright, lulled by the rhythmic swaying of salt water. Their brain is five times the size of a human. Half of it falls into a deep sleep, and the other half is awake. I believe they dream, just like me. I also think that whales are the sentinels of the universe. Looking at them, I remember the words of Franz Kafka from his story “In the Night”:

“Why are you watching? Someone must watch, it is said. Someone must be there.”
