Catalonia is a country of contrasts. The mountains tease the sea, the wind freezes you in the sun, the clear waters carry you directly to the silty depths. Welcome to the land of ghosts. A world in which one should stay within a stroke from one another. Astrée, Saumur, le Bananier and many other wrecks rest in silence. The remains of cabins and the dark of the holds are wrapped in an atmosphere mixing dreams and nightmares. To dive in the world of ghosts is to hover between astonishment and anxiety. Once you return to the surface, do not tell anyone you have seen ghosts: you could be treated for nitrogen narcosis.
