Gurgling and threatening music in the background. Gradually, the music accelerate and turns into a monotonous sound, then we see Croesus, who excitedly rises from the bed. Today was quite an disturbing day. No wonder he have nightmares. However, we forgot to introduce ourselves. This is Krrrek, a 14-year-old dolphin who suffers from insomnia and loves all sorts of abstruse literature. Quite often it turns out that he jumps up in the middle of the night from some fact tormenting his soul, or a nightmare that he cannot sleep for the rest of the night. Perfectly aware of his zero chances of falling asleep again, Krrrek sighed tensely and headed for the exit from his room.
