Waking Life

“We may not know why we sleep, dream or wake up, but these states are never static,” writes author Siri Hustvedt. There is a continuum of perception from unconsciousness to full self-consciousness.

“Understanding waking consciousness, sleep and dreams depends on how the lines are drawn among them,” writes author Siri Hustvedt. “Ernest Hartman at Tufts University School of Medicine proposes a waking-to-dreaming continuum, a range of states that move from highly self-conscious, logical, category bound, sequential wakefulness to daydreaming and reverie with their more fragmented, less logical thoughts to dreaming. … We may not know why we sleep, dream or wake up, but these states are never static.”
