It probably has more to do with Zombies like KN posted, than Christianity. Most Christians have used the phrase shake the living, but only in polemics, not in an apologetics or evangalistic sense. I've not known or ever used the wake the dead. The majority of Christianity I've experienced believes that dead is dead. You wouldn't find biblical basis with the regard to the dead except for talking to the dead and ressurection. I don't think it's Christian based, IMO. Perhaps you as an atheist see it in that sense, because of your selective observation?
"There ought to be a term that would designate those who actually follow the teachings of Jesus, since the word 'Christian' has been largely divorced from those teachings, and so polluted by fundamentalists that it has come to connote their polar opposite: intolerance, vindictive hatred, and bigotry." -- Philip Stater, Huffington Post
