While bieng in the water you feel yourself going deeper until you feel a grip on yourself sensing swift movement. Once you wake up you find yourself on the shore, since then you wanted to know who saved your life so you traveled the sea. When sailing a strong natural phenomenon destroys your ship making you fall into the water
