Libby was about to be burnt at the stake,for being black. The other students in Retrovile didn't want black people in their school,and Libby was the only one,so killing her would fix that problem. They were all calling her nasty names. She was about to catch fire before she woke up. It had all been a dream. Until then Libby had taken it for granted that people treated her like a human being even though she was black. Not anymore.
