Bright amber light gently zig-zags downward and ball of light outside of my home.A bright amber/white light, at least twice as bright as the brightest star, appeared almost due west from my position, 45 degrees above the horizon, and fell slowly downward, disappearing approximately 15 degrees above the horizon. The light's path seemed to gently zig-zag (could be attributed to autokenesis or tired eyes while night driving).I was travelling westbound on M-20, approximately five miles east of MT Pleasant, MI, when this light appeared directly ahead of my position at approximately 11:45 pm. It was extremely bright and compared to meteors, moved very slowly.Could this have been space debris, a bollide or something more anomalous? At approximately 12:30am, forty-five minutes following the sighting, I witnessed a bright flash of light in my upstairs hallway window. I turned to see a ball of light passing the window and lighting up the hallway. My five year old cat responded to this by quickly running up to the wall next to the window and staring intently at a point seven feet up and growling. It took a full ten minutes for him to calm down.
