The Book, the Wolf and the Invisible Agent

Plot: 3 short stories take place in a bar. Laura and Lucia talk about dreams, perceptions and the possibility of writing a book, Murilo talks to an old acquaintance he hasn't seen for a long time and the Invisible Agents talk about existentialist problems and the mysteries that have taken over the bar. The three stories seem very distant from each other, but they couldn't be more interconnected.
