Radiation at a Western University

[nightswimmer]

I was in a drawing or drafting building at a university someplace. The western wall was made entirely of windows, with a single large thick curtain which was open about three quarters. I was standing beside the curtain, but could see it was snowing outside. There were people walking about the room, and those in direct light through the window began to burn. I pulled the cord to close the window and ran with two other girls to a bathroom down the hall. We huddled down and I woke.
I live "behind the pine curtain"in deep east Texas. Perhaps this is the curtain in my dream, but i realized upon waking that what I thought was snow, was indeed ash. Whether this represents a volcano ornuclear event I am unsure.
