Do you think Gregor's metamorphosis could symbolize something beyond the physical? What could Gregor's reluctance to open the door mean? Why doesn't Gregor open the door and speak to everyone face to face? Could his metamorphosis be masking something within his character? Could the fact that he's been changed into an insect symbolize fear in Gregor's character? What might Gregor be afraid of? Is it more than his new appearance?

The door is many things in Franz Kafka's The Metamorphosis. When Gregor Samsa turns into a beetle, it is the door that keeps his secret ... Because of Gregor's transformation, Kafka uses the door as a barrier to showcase Gregor's physical changes. The door is no longer accessible for him; it determines his livelihood.

Explanation:

Gregor's transformation completely alters his outward appearance, but it leaves his mind unchanged, creating a discord, or lack of harmony, between his mind and body ... As Gregor becomes accustomed to his new body, his mind begins to change in accordance with his physical needs and desires.

Gregor Samsa's story is a metaphor for sacrifice ... Indirectly, Gregor's sacrifice that leads to his own destruction also gives his family the strength to leave their passive existence and take control of their lives.
