This near-future sleep addiction tale has been getting around:

The technique that instantly dumped the brain into REM sleep was developed with an eye to military application. … […] It saved the nascent lucid-dreaming device business, then suffering slews of returns and one-star reviews from people who spent real money on headbands that they had to wear all night in the hope of reaching REM sleep. A class spread across generations that didn’t get enough sleep anyway, whose brains were blitzed by blue light and believed eight uninterrupted hours in bed was either a historical artifact or the first sign of a brain tumour.

Some background speculative socio-political concern. (The capitalist war on sleep is advancing into a frontier zone where all manner of strange thing can be expected to turn up.)
