Nightmare Man

The Nightmare Man was a Vishklar from the Seretti dimension.

Biography
The Nightmare Man was able to pass into the universe through the nightmares of Luke Smith, utilising his powerful mind to manifest himself, while at the same time trapping in the dream dimension. Once in the universe proper, he began to induce nightmares in the sleeping populace to further feed him. He was defeated when Luke, Clyde, and Rani shrugged off their fears and stood against him. Weakened, the Nightmare Man was imprisoned in a nightmare of his own: Listening to Sarah Jane Smith telling him how wonderful her son was. (SJA: The Nightmare Man)

Abilities
The Nightmare Man was able to visit Luke in his nightmares, and draw power from them, bringing himself through into the universe. Once he had came through, he was able to place those awake into a sleep, and create nightmares in the minds of those who were already asleep, feeding off of their fear. He damaged K9 Mark IV and Mr. Smith for a short while, and was able to disappear into thin air. Those he created nightmares for were able to enter the same dream as others, which caused him pain.

Behind the scenes

 * The Nightmare Man bears a similarity to the Pied Piper, (SJA: The Day of the Clown), the Dream Lord, (DW: Amy's Choice) as well as the Ghostmaker, (TW: From Out of the Rain) the latter who was also portrayed by Julian Bleach.
 * The Nightmare Man's goal is identical to that of the Bodach, (K9TV: Dreameaters) who were also an incorporeal species feeding on nightmares tackled by K9. However unlike the Nightmare Man who can manifest himself if he becomes stronger, the Bodach can only possess a Human avatar.
