A bright gold glow during a silvery lightning storm

It was night, around 9 pm. There was a big dramatic storm, with thunder and lightning. The lightning gave a cold light. I lived on the top of the hill on 12th street east of Lamar. I was lying on my back on the floor with the lights out, with my feet facing the french doors, watching the display. All of a sudden there was a bright gold light that filled the windows. It wasn't a lightning bolt, and I waited for it to be over, but it stayed and stayed. I got up and got dressed, thinking something really big was happening (something I had never seen before, I wasn't sure what, but something big) and I might have to go outside. During all that time of deciding to get up, finding my clothes, and putting on shoes and socks the light just stayed, glowing warmly, filling the whole sky. Then it was gone.
