Question

Which event in Franz Kafka’s The Metamorphosis can be considered surreal?

Gregor’s father kicking out the lodgers
Grete’s moving violin-playing
Gregor transforming into an insect
Gregor’s mother procuring a new job

Answer 1

Well, obviously the answer is 'Gregor transforming into an insect'. It doesn't seem real that a person could just turn into a bug, therefore that is the answer, it is surreal. 

Answer 2

The answer is: Gregor transforming into an insect.

Franz Kafka´s novella, Metamorphosis, presents us with his famous character, Gregor Samsa, who one day, at the very beginning of the story, woke up to find himself, for no apparent reason, turned into a horrible, and hard to define, kind of bug.

Although Kafka´s work is not usually characterized as surrealist, there are passages where his treatment of absurd themes certainly exploit oneiric, fantastic, unexplainable, and spontaneous manifestations of the imagination (all traits of surrealism) for the benefit of the narrative.
