Very slow moving bright light that "jumped" in a zig-zag pattern at times.

I'm a sky-watcher. While walking my dog, I spotted a very bright light high in the sky, not Venus. It moved very slowly across the sky from S to N. At times it seemed to stop...then move on again very slowly. I watched for 10 minutes when suddenly, it did what I call "jumping" or "skipping" in short start/stops, moving towards the E slowly. I've seen other UFOs do the same thing. It is like it was jumping from one spot to another rather than in a linear pattern smoothly. It was still there when I went indoors, jumping/skipping towards the E. A few times the light skipped in a zig/zag pattern as it moved along. The light must have been a huge object because it was so bright and obvious in spite of being so high in the sky.
