Planet (Last Christmas)
From Tardis Wiki, the free Doctor Who reference
This planet was a very warm and damp rocky planet. It there was a thin fog and it sounded like there was lava nearby. The Doctor appeared to have had some business to do on the planet when he was attacked by a dream crab. He later woke up from his dream, the dream crab died, and he took the TARDIS away from the planet. He only later realized that it was a dream within a dream and woke up on the planet, the dream crab died, and he took the TARDIS away from the planet. (TV: Last Christmas)
Behind the scenes
- This planet was possibly the same planet that the Doctor led Clara Oswald to believe she was on, via a dream patch, while threatening the Doctor to save Danny Pink from death and throwing away the TARDIS keys into what she thought was lava. (Dark Water)
