cruise ship captain

I was on a beach and I ran by someone's towel where they'd left their cooler and things and grabbed a bag of sandwiches. No one was around. I took it and ran to a jet ski, which I stole. I felt so thrilled and horrified of getting caught. I drove so fast. I drove to a harbor where a giant cruise ship was being boarded. I saw the captain of the ship riding his jet ski towards the ship. I thought he was going to suspect that I was a thief who was about to sneak on the cruise ship. He turned his head slowly and looked at me sternly. I smiled and waved. He turned his head back. I rode to a long space under the boat. It was like a carved out tunnel underneath the ship. I have no idea what purpose it served. Maybe to make the boat more aerodynamic. I parked the stolen jet ski in the tunnel and started to eat my stolen sandwiches. The ship captain drove into the other side of the tunnel, coming towards me slowly. When he got to me, he turned the engine off and sat there staring at me sternly. I stared back. It was a stare-down. I gave him the most stern, intense look I could. He returned the look. He said no words. Then I bent backwards and started limbo-ing under the tunnel ceiling. It was a challenge to him. He did the same. I clapped my hands and did some crazy movements with my arms. He did the same, a mirror image of me. I woke up.
