Davey Morgan was an elderly man who lived in the main city centre of Cardiff. He was commonly despised by children who laughed at him. He was an ex-soldier from World War II and often remembered the terrifying events.
During a stormy night, he had a terrifying dream about meeting an alien at the front door after answering some heavy taps. He woke up to discover that the exact same taps were occurring in the real world. Heading downstairs, he discovered it was merely his back door, which he hadn't closed properly the night before.
