Now how does all this relate to the Harry Potter series?

I know you're thinking it- How exactly does this all apply to Harry Potter? If you think about it, the answer is kind of obvious.  The Mirror of Erised!  In Harry Potter and the Sorcerer's Stone, J.K. Rowling uses the mirror to give her characters more depth, and also to create chaos in their lives. The Mirror of Erised is a manifestation of their deepest wants, dreams, and desires. While Lacan says that when you look in a mirror you see that you are lacking something, Rowling's Mirror of Erised shows you exactly what you are missing, making the feeling of loss and lack even more profound.
