This is a NPR interview with Toni Morrison from 2011. She discusses her take on ghosts, as well as how her own experiences influenced her novels. Her take on spirits is definitely unique. She says, "I think of ghosts and haunting as just being alert. If you are really alert, you see the life that exists beyond the life on top." She also discusses how she never recognized how her own experiences had influenced her work. She actually says she's "loathes" people who ask if her characters represent her or her life. In fact, she had actually seen a ghost walking out of the Hudson River (5:30 on the interview). Ring a bell?
