The Dream Lord
The Dream Lord was the dark side of the Doctor, who seems to have control over dreams. He was created by psychic pollen that gotten stuck in the TARDIS, and awoken as it was warmed up. The Dream Lord was created by the pollen from the Doctor's inner darkness. He trapped the Doctor, Amy Pond and Rory Williams between two dream worlds, telling them they would have to choose between them. However, the Doctor eventually realised that both weren't real, and managed to return them all to the waking world. After removing the pollen, the Doctor saw the Dream Lord's face in his reflection in the TARDIS console, smiling slyly at him. (DW: Amy's Choice)
Notes
- The Dream Lord shares some similarities with the Valeyard; Both are representations of the Doctor's dark side, and they both have great hatred for him. Indeed they may indeed be incarnations of the same force.
- The Dream Lord also has similarities with the Celestial Toymaker and The Valeyard.
