Is Gregor's transformation real or is it imagined? How does Kafka's language and writing style affect its believability?

this is what i put and it was correct

it's a way for authors to communicate with reader in this time period. books from the past can teach us about life.

the narrator is a first person, participant one, who describes in the simple past tense important and difficult events in his earlier life. he also provides temporal markers as the month (january) and the time (12: 30 pm). finally the account of his experience is very detailed, to the extent that a participant narrator would talk the same way about his experiences. a good example of such detail is the mention of the “bovril ration” which historically was a native american food adopted by european explorers in arctic and antarctic regions due to its high level of calories.
