1. The Power of the Mind:
* Telekinesis: Carrie's ability to move objects with her mind is a supernatural element, even if it's not explained through conventional supernatural means. This power is born from her emotional state, making it a form of psychic ability.
* Mental Impact: Carrie's rage and terror have a profound, almost supernatural effect on the people around her, causing them to panic and flee. This suggests a powerful emotional force at work.
2. The Supernatural as a Metaphor:
* Carrie as a Witch: Although not explicitly a witch, Carrie's outcast status, unusual power, and violent outburst at the prom evoke comparisons to traditional witchcraft narratives. This metaphorical association enhances the story's supernatural elements.
* Symbolism: The pig's blood used in the prom prank, while a realistic detail, can also be seen as a symbol of Carrie's perceived 'uncleanliness' and the cruelty she faces, adding a layer of symbolic significance.
3. The Uncanny and the Unseen:
* Carrie's Past: The book touches upon the mystery surrounding Carrie's past and her mother's fanaticism, creating an unsettling atmosphere of the unknown.
* The Threat of the Unknown: While not explicitly supernatural, the fear and paranoia felt by those around Carrie, driven by their fear of her power and the unknown, creates a sense of the supernatural.
In Conclusion:
While "Carrie" doesn't delve into traditional supernatural elements like ghosts or magic, it skillfully incorporates aspects of the uncanny, the power of the mind, and symbolic narratives that enhance its horror and contribute to the feeling of the extraordinary.
