Plot
Rose has a nightmare in the TARDIS about a fisherman being killed by a hideous monster. The Doctor traces the source of her nightmare to present-day, on a Welsh island called Ynys Du (literally 'Black Island'). There, they find a dead fisherman, the same one that died in Rose's nightmare.

The Ynys Du Village has been haunted by monsters each night, and all the children are plagued by nightmares. The Doctor discovers a massive psychic transmitter in Black Island's lighthouse, while Rose discovers that the culprits are the alien Cynrog.

The psychic transmitter is causing the children in the village to have nightmares, then it extracts the monsters from their nightmares and manifests them in physical form (which explains why the monsters only appear at night). However, the Cynrog are using the children's monsters to create a suitable body for their reincarnated war god, Balor.

Balor's spaceship crash-landed on the Ynys Du coastline in the 1930s, and Balor died in the explosion. However, eight children witnessed Balor's dead, and a segment of Balor's mind each passed into their own. The Cynrog have been gathering the children (who are now old) to restore Balor's consciousness (one of them is Nathanial Morton, who owns the nearby rectory).

However, the Cynrog attempt to restore Balor using only seven of the eight fragments, and so Balor becomes wildly unstable and kills most of the Cynrog. However, it is revealled that Morton has turned into Balor, and now intends to rule the world. However, Rose reverses the psychic transmitter's polarity, so instead of using the children's nightmares, it locks on to the psychospore of the adults of the village, and since they don't dream about monsters (instead, things like interest rates, parking spaces, etc), Morton-Balor loses his physical form and dies.
