What if an entire continent vanished beneath the waves in a single night… and that moment helped create Britain?

In this History for Sleep episode from Sleepy Time History, drift off as we explore Doggerland, the lost land that once connected Britain to Europe. Discover how a massive undersea landslide off Norway, the Storegga Slide, unleashed a tsunami so powerful it reshaped the map of Northern Europe 8,200 years ago.

We’ll journey through:
• Life in Mesolithic Doggerland before the flood
• How the Storegga tsunami formed and raced across the North Sea
• The drowning of Doggerland and the long separation of Britain
• How scientists use sand, peat, and seafloor clues to reconstruct this ancient disaster
• Echoes of great floods in myth, memory, and modern coastal risk

Designed to be calm, atmospheric, and immersive, this video blends relaxing narration with deep time history—perfect for sleep, study, or quiet late-night curiosity.

Note on Process & Accuracy:
Every story on this channel begins with a deep respect for history. We act as directors and editors, using AI tools to help research and draft the script while we shape the narrative and verify facts. The narration comes from a digital replica of a professional voice actor, and the images are individually crafted artistic impressions using AI. Even with these tools, creating a story of this depth still takes hours of work.

Please note that while the narrative is thoroughly based on historical research, its primary purpose is storytelling for entertainment and relaxation. As such, it is not intended to be used as a formal academic or scientific source. Thank you for your trust and support.
