What a Big Sea Monster

I had a dream yesterday, and it's hard to describe the atmosphere. It felt like deep sea fear, giant fear, and Cthulhu. I dived in a vast sea. As the depth became deeper and deeper, the water began to layer. The vibrant fish around me gradually disappeared and were replaced by giant sea monsters that were rare but symbolized loneliness. The sunlight was replaced by darkness, but sea monsters that were darker than darkness could be seen wandering around. The sea had no bottom and was a black hole.
