I saw a star-sized light zig-zagging high in the dark morning sky.

At 6:20 am I let my dogs out. It is a very clear morning. The stars are very visible and clear. I look up every morning to check the stars and sky out. Today, I looked up and saw a star-sized object moving at a very high rate of speed. It zig-zagged. I first thought it was my imagination the way it zig-zagged. I kept watching, and no doubt, it was zig-zagging, like it was avoiding objects in its path. As I watched, it disappeared into the dark sky as if it was climbing higher. It was visible for maybe, 3 minutes. It looked just like a star.
