We move through the world assuming our senses give us a stable, reliable picture of reality. Yet for those experiencing psychosis, that picture can fracture into illusions, vivid hallucinations, and distortions so powerful that they blur the boundaries between the imagined and the real. In this illuminating book, one of the UK's leading psychiatrists, Professor Femi Oyebode, draws on real clinical stories, memoirs, fiction, ancient myths, and folklore, to show that these unusual experiences are not only clinically significant but also shape art, storytelling, and our understanding of consciousness. By tracing the deep links between the brain mechanisms that enable everyday perception and those that give rise to pathological experiences, this book shows what these disruptions can teach us about how we see, hear, and experience the world. Engaging, compassionate, and thought-provoking, this is essential reading for anyone curious about the mysteries of how our minds work.
