"The Fog Horn" by Ray Bradbury
Today I read "The Fog Horn" by Ray Bradbury. It is one of my favourite short tales that I've ever read. The story starts with a conversation between Johnny and McDunn who is the keeper in a lighthouse. In this conversation, McDunn starts to think about the mysteries that could exist in the sea and he told Johnny about a strange phenomenon that he saw once while he was keeping the lighthouse on a misty night. On that occasion, he switched on the lights and the foghorn and he could hear an anguished scream from a far place, apparently beneath the sea.
Back to the present, he said to Johnny that now could be the day where he could switch on the foghorn again and both could feel the same experience. Then, he did it and they heard the sound from far in the sea's horizon and they started to think about the loneliness of some creatures and how immense could be the life beneath the sea where the time is rolling by slowly.
After a moment, the creature starts to approach the lighthouse and when they switch on the foghorn the sea monster realised that it is not other of his specie, so attack violently the structure. McDunn and Johnny survive but again start to reflect on how difficult could be for the creature to be conscious of that he lives alone in the world and he could be the only one of his species.
