You were a Mosasaurus.

You were in deep depths of the Atlantic Ocean.

There was a thunderstorm and you felt waves coming over you and a glimpse of a bottom of a ship.

There were people on the ship hunting for fish to eat so they had a cage with bait in and tossed it into the ocean and the strong waves hitting the ship as they stay balanced.

There were around 8 people on board on the large ship oblivious and kept baiting and fishing.
