This was very interesting to read. Myself have seen 'concentration' camps in an asian country, and 'we' got killed off as flies on glue paper. Fast killers, soldier like in this case. On the plus side, the camp blew up, and I managed to escape (only after being killed 3 times and jumping bodies), ran towards some seaside city, old eastern style wharf, hiding on the lower level before entering a white marble room full of "nice" people who looked at me strangely. One hell of an action filled dream.
Some relevant details perhaps: Grass was green, sky was blue, little wind, quiet sea. Had the dream mid summer this year.
Just wanted to add it to see if it had any relevance to any you have had
And a book would be an idea
Keep it up!
