Doctor Who: 12 Unanswered Questions From Last Christmas

8. Why Didn't Professor Albert Wake Up?

He died. Sorry to be blunt about it, but it's true. That was the whole point of the Dream Crabs, who are really called the Kantrofarri, by the way, if you want to get personal. They certainly do. Feeding off telepathic images of themselves, they invade your mind and suck out your brain through a straw but they put you in an anesthetic-like dream state while they're doing it so you don't feel any - or as much - pain. Every cloud has a silver lining. In this case their victims were quite literally dreaming of a white Christmas and Professor Albert was the only one who succumbed to them. He seemingly would've died in his sleep in the real world which means there's (at least one) Dream Crab still out there getting ready to enslave the human race while they're sleeping. You'd better sleep with one eye open tonight. Don't worry, though, because the Easter Bunny is on the case.
