There were a few lights moving around the sky rapidly. The light would come into view, drop/raise drastically fast. Not normal speed

Myself and my neighbor both spotted a bright light (and a few at one point) over the course of 90 minutes. The lights were moving, dropping and raising and zooming around at drastic speeds. It wouldn’t be feasible for a normal aircraft to drop from one point in the sky and end up much lower the quickly. The light didn’t follow normal aircraft movements. I didn’t realize until many days later that my neighbor and I both witnessed the same lights and movements, as we weren’t together when we saw it originally. We both reported seeing the weird lights and movements.
