The kind of fiction by gabriel garcía márquez in which otherwise true-to-life events take place in a world of supernatural events is called magical realism.
Magical realism shows fantastical events in a realistic tone. Characters are given fantasy traits like levitation ( a priest levitating after drinking a cup of hot chocolate in Gabriel Garcia Marquez One Hundred Years of Solitude). Writers do not create new worlds as Tolkien, but reveal the magic in this one ( a girl doing the laundry and ascending to heaven in the imaginary town of Macondo)
