It's the end of Halloween here in US Pacific Time and I just was re-reading Kafka's The Metamorphosis.
I think Gregor Samsa was human the entire time. He had a mental break.
1) He was not an "insekt," he was an "Ungeziefer," from the Middle High German "ungeziber," an animal unfit for sacrifice.
2) Kafka insisted that Gregor "cannot" be drawn. A great way to maintain that ambiguity.
3) The narrator is a third-personal Gregor until he dies. Then it's a conventional omniscient narrator...
