Es probable que las pesadillas sean la experiencia que más nos acerca al terror en nuestra vida cotidiana y este volumen contiene varios ejemplos, como el miedo a quedarse encerrado en un lugar del que no se puede salir en El callejón, la angustia provocada por los laberintos en Un laberinto insoportable, o el pánico a caer al vacío en Caídas. Incluye, entre otros relatos, La abusona, donde una niña cruel se dedica a maltratar a un amigo suyo y Un desertor en casa, una historia de venganza, ambientada en la posguerra e inspirada en la vida de Ana Frank.
