Imagine this: a sickness where millions fell into a deep slumber from which they never woke. Of those that did, many remained trapped in a cage of their own bodies, unable to move or speak but fully aware of the world around them. Imagine that this sickness appeared suddenly, without warning, and spread across the globe, affecting millions in just a few decades. Then, just as quickly as it emerged it disappeared. Survivors were left to suffer, eventually forgotten, while hundreds of questions re...
