When Animals Dream

Trade Paperback

The Hidden World of Animal Consciousness

A spellbinding look at the philosophical and moral implications of animal dreaming.

Are humans the only dreamers on Earth? What goes on in the minds of animals when they sleep? When Animals Dream brings together behavioural and neuroscientific research on animal sleep with philosophical theories of dreaming. It shows that dreams provide an invaluable window into the cognitive and emotional lives of nonhuman animals, giving us access to a seemingly inaccessible realm of animal experience.

David Pena-Guzman uncovers evidence of animal dreaming throughout the scientific literature, suggesting that many animals run reality simulations while asleep, with a dream-ego moving through a dynamic and coherent dreamscape. He builds a convincing case for animals as conscious beings and examines the thorny scientific, philosophical, and ethical questions it raises. Once we accept that animals dream, we incur a host of moral obligations and have no choice but to rethink our views about who animals are and the interior lives they lead.

A mesmerising journey into the otherworldly domain of nonhuman consciousness, When Animals Dream carries profound implications for contemporary debates about animal cognition, animal ethics, and animal rights, challenging us to regard animals as beings who matter, and for whom things matter.

'When Animals Dream ranges from fascinating to thrilling. A very accessible, penetrating, thought-provoking book that makes us see other-than-human minds in a whole new light.' Carl Safina, author of Beyond Words: What Animals Think and Feel and Becoming Wild

'Octopuses dream. Rats suffer nightmares. Chimps trained in sign language talk in their sleep. This revelatory book shows us that animals minds, like ours, are gloriously nimble, vivid, and complex, even during sleep. This is thrilling, essential reading for all of us seeking to expand our understanding of the wonder of consciousness.' Sy Montgomery, New York Times bestselling author of The Soul of an Octopus: A Surprising Exploration into the Wonder of Consciousness
