St Nicholas's Hospital

St. Nicholas's Hospital was a London hospital the Doctor visited on late Christmas Eve 2006. At the facility, the Doctor was checking in on Daniel Francis Thompson, a young boy who was in a coma following a traffic accident. Somehow, the Doctor's TARDIS had been pulled into the boy's subconscious struggle for survival. In the boy's mind, but in a way real to the Doctor himself, the two made a tour of various Christmases of the past. Once the Doctor deduced that Dan wasn't in fact physically present in the TARDIS, he sourced Dan's true location in the A&E department of St. Nicholas's, and instructed the projection of Dan to fight for life. At the stroke of midnight, Daniel emerged from his coma with the Doctor by his bedside. (The Sunday Times: "Deep and Dreamless Sleep")
