This is where you write about what makes you such a witch! What witchery have you committed in your current lifetime? Did you take off your hijab in a community where everybody would condemn that? Or did you choose to wear it during a time or in a place where it was not socially acceptable? How have you gone against society's norms? Write it in free form and don't worry about how you come across. Just write and write and write.
As Ernest Hemingway would say "Write drunk. Edit sober"
