What Happened ?

You suddenly realize you're walking down a narrow country road at night,
and you're alone. Why are you walking at this time of night ? Where are
you going ? You stop, and turn around, and see a huge orange glow over
the hills that shimmers intensely in the shadows. Did something happen
back there ? Your hands go into the pockets of your jacket and you pull out
two items from the left pocket and one from the right and squint at them in
the dark. The first item is a pin with the letters ATS on it. The second item
is a book of matches with notes written all over it. And the third item, from
the right pocket, is a small condensed version of the Bible. There is
nothing else, nothing to even tell you who you are. So . . what happened ?
