It was primarily set in 'not too distant' future (within the next 50-100 years I'm guessing) and involved a billionarie industrialists scheme to cleanse the world of filth and reincarnate people by redirecting their 'souls' upon death into 'Carnations' (a type of crystalline battery) which was then inserted into a 'Shell' (initially an almost featurless gray organic structure vaguely modelled on the person who'll eventually inhabit it; Shells then took on the fuller features of the person once the Carnations were inserted and activated. Then the persons 'soul' powered and shaped the finer details and personality of the Shell).
There was a hardcore religious group called 'The Redemeers' or 'Redemptionists' who on the final day would help people move on to the better life. They were cloathed in long brown hooded robes, with somekind of kevlar armour woven into the fabric, and carried some of the biggest firepower I've ever seen! They were also based in what seemed like some kind of medieval keep which was kinda cool. The Redemeers were opposed to the billionaires plans (although to be fair I'm not sure they actually knew about them) but were preparing for the 'Final Day' along with other covert groups of their group scattered across the world. They were a bit of a mix between Mad Monks and The Templars to be honest and had many high ranking/profile society members amongst their ranks, including the Emperor of Polska.
The dream contained cloning, shielded islands, nuclear destruction, wastelands, Purgatory Paper, hopes and dreams, betrayal, and one of the best twists at the end that really blindsided me!
I'll try and write-up more later (I've already started to do so but need to get ready for work) but WOW. I ams o glad sometimes that I live inside my head :p
