I find myself shopping at the grocery store. I am near the last isle in the corner which I would like to reach but am prevented from doing so for some reason (there must be a delay). I look through the cracks in the isle to see what is visible on the shelf, but the last isle is at least two rows over. When I finally get to it there is a gentleman with a device set on the shelf. On the device is a knob which he controls. It apparently has the ability to increase radioactivity. As it starts going up and up, I warn him he'd better be careful (and in the process wonder why someone would do such a thing so calmly and calculated). I quickly leave the area, heading to the front of the store carrying an old civil defense Geiger counter I bought some time ago. Along the way I measure 30 Sieverts/hr and it's still rising. I can feel the "heat" of the radiation itself at this point (symbolic?) and warn others to move to the front of the store and beyond if they don't want to be affected.
Part II
I'm in a shelter, bunker, or other dark place/room. I and some others are anticipating a destructive event of some sort. An explosion, a nuclear attack, or perhaps a destructive storm? I play out in my mind how the moment of death would occur and reach the conclusion that, given how quickly I would be torn apart, it would not be that bad!
Part III
I am being shown a "map" which reveals lush grassy lands. I am told of at least one place that would be fertile and safe, that which used to be the "land of faeries and elves". I believe the map to represent Finland in particular, Scandinavia at large, Iceland and perhaps some other areas of Europe represented as green.
I am left with two waking impressions in the form of phrases: "A director is dead" and "Admiral Nimitz walks the plank".
Edit: This link shows what the radiation fallout from a typical nuclear blast would look like. Interestingly, the first circle represents 3,000 REM, or 30 Sieverts.
