"Once I had a nightmare about that room. I was walking down a long hall and saw the curtains on a doorway at the end. Even though I was dreaming, I knew exactly where I was, and I felt an icy chill run through me. I wanted to run away, but something was pushing me toward the curtains, and I started to scream for John. 'Help me . . . help me . . . please...' Then was when I woke up screaming. Right there and then I should have known the dream was an omen of death" (142-143).
