The ghost submarine USS Jeoeric Happens
A submarine where the crew members all died and the submarine was destroyed had left behind a specter of its formal existence along with ghostly crew members on the USS Jeoeric happens. People who see this submarine when diving have experienced unease and when they look into the windows to see the ethereal crew members they have a heart attack and become a member of the unliving crewmates. Then it goes onto the next continental sea area.
