Shimmer of Blue Light

I remember a shimmer of blue light I saw a night long ago.
The sun was not up yet, but the blackbirds were singing,
they didn't know the day was gone.
My shoes were aching from hours of dancing,
so I took them off and walked barefoot over the muddy path.
Shadows were dancing before my feet.
Suddenly, the sun came through the trees,
and I was blinded by a shimmer of blue light.
