The 36th episode of The Sarah Jane Adventures airs on CBBC, starring Elisabeth Sladen (Doctor Who). 
Encouraged by one of his teachers to take his A-levels early, Luke not only succeeds with flying colors, but is accepted in Oxford at what seems like an alarmingly young age (not taking into account that he’s not entirely human). Suddenly, he’s only days away from moving away from home, but something else is scaring him: repeated visits from an entity that he’s sure is going to try to destroy the world. This man appears only in his nightmares and warns Luke that the boy’s nightmares are feeding the being power. And then one night, Luke discovers that he isn’t just dreaming these encounters: the Nightmare Man is real.
