And as the lyrics of The Waterboys' 1980s hit, The Whole of the Moon, came through Thomas's earphones, he experienced six flashbacks - each triggered by the one before.

For the 30-year-old, this was an extraordinary moment. One he had craved for 10 long years - ever since his entire memory had been wiped when he was hit by a car. "It was the most magical thing ever," he says of the memory-chain.

"I was sitting on this weird blue floor and I could see this silver radio. Then, I was in another place and I was holding this man's giant hand… and then there was another memory."

He recalled a Christmas tree, towering over him. "There was a woman standing, and she was young and she was smiling and she didn't have grey hair. It was my mum and I was her little boy. And it was real."
