What are the two seemingly supernatural occurrences in The Scarlet Letter?

In Nathaniel Hawthorne's The Scarlet Letter, two seemingly supernatural occurrences are the appearance of the scarlet letter "A" on Hester Prynne's chest and the meteor that creates a glowing "A" in the sky. The letter, which symbolizes her sin of adultery, seems to take on a life of its own, affecting her identity and relationships. Meanwhile, the meteor's formation during Dimmesdale's election sermon is interpreted by the townspeople as a celestial sign, reinforcing the novel's themes of guilt and moral ambiguity. These occurrences highlight the tension between reality and the supernatural, deepening the characters' struggles with their inner demons.
