““So there you have it: hearing voices at sea is not a pathological condition. It’s quite normal. Welcome to the world of illusions at sea. Of mirages, looming, towering, stooping and sinking. Of moons that change size, suns that change shape, horizons that bend, lights that change colour, and sounds that play hide and seek. Of waves that speak, ships that effervesce and whales that turn into baby elephants. For the sea has a lobsterpot full of tricks and illusions to confuse and beguile even the most rational 21st century sailor.””
