I was on vacation and went for a walk to the beach at night. I was sitting out on the pier they have at the beach and noticed a bright round light out in the dark night. The light was hovering just above the water, it looked like a ship light until it started to move back and forth really fast as far as I could see, First to the right and back and then to the left. I couldn’t believe what I was seeing so I stood up and it stopped and started to come towards me so I left the beach and ran back to my room. The beach was empty that night so I was the only one who witnessed it.
