Laypeople think of wake, sleep and dreaming as distinct states of the mind/brain but “in-between”, hybrid states are recognized. For example, day-dreaming or, more scientifically, the default network occurs during wake. Equally, during sleep, lucid dreaming in rapid eye movement (REM) sleep presents as another hybrid state. But hybrid states are usually temporary. This book explores the possibility of an enduring hybrid wake-sleep-dream state, proposing that such a state may engender both creativity and psychopathologies. REM sleep is hyper-associative. Creativity depends on making remote associations. If REM sleep and dreaming begin to suffuse the wake state, enhanced creativity may result. But moderate to severe interpenetration of wake, sleep and dreaming may engender psychopathologies – as the functions of wake, sleep and dreaming are partially eroded.

YOU SPEND ABOUT A THIRD OF YOUR LIFE DREAMING. HAVE YOU EVER WONDERED WHY? 'THIS BOOK WILL CHANGE YOUR LIFE' Lewis Howes 'TRANSFORMATIONAL' Julia Samuel 'OUR POET LAUREATE OF NEUROSCIENCE' Greg Whyte 'AN INSTANT CLASSIC' Bryan Fogel Dreams are a source of mystery. They have changed the course of individual lives and the world, spurring business deals, inspiring art and scientific breakthroughs, triggering military invasions and mental breakdowns. Yet the source of dreams is not mysterious. They are the product of an extraordinary transformation that occurs in the brain each night when we sleep. In this pioneering book, bestselling neurosurgeon Rahul Jandial delves into the dreaming brain and shares stories from his own practice to show the astonishing impact that dreams have on our waking life. He explains how dreaming of an exam might help you score up to 20% higher, why taking a long nap could make you better at problem-solving, and even that certain dream disorders can warn you of serious diseases like Parkinson’s years ahead of other symptoms. He offers clear and compelling advice, backed by new research, to become a lucid dreamer, understand your dreaming patterns and unleash their creative power. Sharing the very latest discoveries in modern neuroscience, This Is Why You Dream provides answers to some fundamental questions: Why do we dream? How do we dream? What do dreams mean? And perhaps, most importantly, do we sleep in order to dream?
