Answer:
He shows that the situation he is going through is not real and that he is delusional about it. This shows how Gregor thinks of himself as a negationist and believes only in rational things.
Step-by-step explanation:
This question is about "Metamorforse" where we meet the character Gregor Sansa who one day wakes up transformed into a giant insect.
The situation that Gregor finds himself in is completely surreal and anyone would be terrified to live in a moment like this, but not Gregor, he is very calm because he does not believe that this is actually happening. For Gregor, having the body transformed into a body of an insect is an illusion and he decides not to confront this reality, but to wait for it to pass and he will be as he was before.
