Ever had the feeling you’ve been asleep or even dead—and woken to a world that’s changed beyond belief?

I have died a few times, but only for short spells. The official record is 47 seconds (I have the hospital printout showing the flat-line recorded in intensive care), so not enough to give that Rip Van Winkle Effect. Why is it, then, that I am so shocked nearly every day by a sudden lurch into what seems like Blade Runner Country? Why does being awake now seem like being stuck in a bad dream in 2050?
