Dream control is inexact, though. As Robert Waggoner, the author of Lucid Dreaming: Gateway to the Inner Self, puts it: "The sailor does not control the sea, and neither does the lucid dreamer control the dream." Gackenbach, too, has found that her subconscious has a way of fighting back: "I was sitting on a bench in Central Park, and I knew I was dreaming. A beautiful woman in a white hat was walking by. I decided to try to change her hat into a monster, but I couldn't. Instead, she changed into a wolf and bit me."
