The science of dreams and nightmares - and their astonishing impact on our waking lives.

Dreams slip away when we wake, their remnants jumbled and only half-recalled. Some leave behind surreal sensations or bursts of creativity. Others leave us shaken.

But why do we dream at all? How do our bodies interface with our brains while we sleep? Why do some dreams go bad? And how can we harness our sleeping minds to improve our waking lives?

Pioneering researcher in sleep medicine Dr Michelle Carr unlocks the science behind the sleeping body. Drawing on her expertise in nightmares, lucid dreaming and the cutting-edge field of dream engineering, she reveals how we can revolutionise our sleeping - and waking - health.

Includes an exclusive bonus section with practical techniques for lucid dreaming, nightmare resolution, and dream engineering.
