I'm waiting for O'Reilly to take a note from "Mind Hacks" and publish "Dream Hacks" on how to induce and get better at lucid dreaming and then using the dream state to ensure maximum rest and recovery but still get "work done".

I see this as a potential benefit for when we start building (better) neural interfaces to our brains - "network" segmentation of sleep vs work areas to allow brain-to-computer work to continue whilst the body recharges.
