It is a 'Collection of Grimm's Fairy Tales.' 'Cinderella,' 'Little Red Riding Hood,' 'The Little Mermaid,' 'Rapunzel,' 'Snow White,' 'Alice in Wonderland'—it was a mysterious volume containing stories everyone knows. You pick up the weathered book, sit in a nearby seat, and begin to read. After a while, you are suddenly overcome by an intense drowsiness and lose consciousness.
