Writer Siri Hustvedt is a migraine sufferer and will often experience aphasic dreams. As she enters the slumbering state she will have hallucinations. As she says, these "are anomalies, no doubt, tics of the nervous system that affect some, not all, but they could well help explain more general human qualities—who we are, what we feel, and how we see. I suspect that everyone has a few Lilliputians in hiding. It may be just a question of whether they pop out or not." Siri Hustvedt is a novelist and essayist. In both her fiction and nonfiction, she has explored the ambiguous boundaries between the imaginary and the real, waking life and dreaming, and the brain and the mind.
