In the Sleeping Worlds, real time does not flow. Unless one restores the world by waking it from its slumber, it will stay locked in a dream forever. Thus, you may encounter familiar faces... but they are just figments of the dream. In actuality, they are sound asleep - trapped within a world that is also sleeping. What's more, whilst someone may no longer dwell in the real version of a world, dreams may paint a fuller picture, and restore what seems to be missing.
