The waves come up with a loud smack! They’re supposed to be lulling... Ripples rock the boat, port side starboard, port side starboard. I drift off into an enchanting dream. Bang! Quite an annoyance if I might say. I drift off into a boring dream. Bang! This time sadness of deprived sleep overcomes me. I drift off, into a nightmare. A storm overhead, people chasing me. Run! Run! I hide. Bang! They found me. Bang! Run again. Hide again. Bang! Port Side starboard, port Side starboard.
Port side is a sailing term meaning left side of the boat, and starboard means the right side of the boat. The bangs stand for the slapping of the waves.
