PROMT NINE

Hello!! Sorry this isn't good. I have no ideas haha :(

This prompt is about someone who finds a mistake in their reality by looking into a mirror. Expand this idea!! How is the protagonist's reflection different? What happens? Is it a lead to another dimension? Are they seeing their true self? Are they in control of this reflection? Are they the puppeteer of their own reflection?

If you wish to use this passage/prompt then please tell me/give credit :)
