Wow!!!! I had a dream that was exactly the same!!!!!!!! For me, I was not aware of the exact location I was looking at, but the same thing...the mushroom cloud, the terror of my imminent death...the light making it's way to me, and then watching myself fade. I did not get to the point where I felt peace, just blank... My last thoughts were, "so this is it..." I thought of my children, and then it was over. Very, very strange. This dream occured about 2 months ago.
