The interconnected awareness of so many people is gaining a sentience of its own - but it may have been planned that way - and physical reality may just be a shadow of it. Can Lain stop it? Probably, but that's not what the series is about. Can she understand what is happenning to her, and keep her friends? Barely, with a couple of really big false starts - but that's not what it's about either. Can Lain shrug her shoulders as the world around her freezes, and go back to screaming out of your TV? Can the swirly graphis and the eerie electronic soundtrack set your hair on end?
(Nice touches: To *Be* Continued. It so looks like 'OS' should be in place of continued...)
