Is magical realism real or just realistic? What's the difference?

In magical realism the world appears much like our own, but also includes an element of the extraordinary. In Franz Kafka’s "The Metamorphosis," Gregor Samsa awakes one morning to find he has turned into a giant insect. In Stacey Richter’s "The Cavemen in the Hedges," cavemen scurry in backyards, rummage through trash, and adore shiny objects. In Gabriel Garcia Marquez’s "A Very Old Man with Enormous Wings," Pelayo finds an angel with "huge buzzard wings, dirty and half-plucked" in his courtyard after a rainstorm. Still, the extraordinary is firmly rooted in the ordinary. "A Very Old Man with Enormous Wings" is populated with human characters, such as Pelayo’s feverish newborn and the local priest, Father Gonzaga. And the story is anchored in details the reader recognizes from her own reality: rain, sea and sky, a chicken coop.
