Down on the escalator to the subway, Nestor notices a strange smell coming from below. Could this be a terrorist attack, like the sarin attack on the Tokyo subway? Nestor tries to save himself, but suddenly realizes that everything is happening in a dream that he is having. The consciousness of the sleeping Nestor wanders in the sleepy world. Images-characters, men, women, and sometimes objects appear and disappear around. They act as if they are endowed with free will... Nestor wants to go upstairs and go out, in other words, to wake up, but for various reasons he does not succeed. In principle, his wanderings in the world of sleep can last indefinitely.
