Dreaming of ship wrecks

In my dream I was coming out of my sleep state from dreaming about fish, as if I was awake but I had not opened my eyes yet. I was looking through a telescope out into the ocean, like looking through a port hole. I saw many ship out in the ocean, the sea was calm, but the ships were all wrecked, like ghost ships or that they had been in battle many years ago. I woke.
