Anyway, your story is very interesting. Your description reminds me of some strange lights that are seen periodically in a couple of parts of the US. The things here seem to be some sort of electrostatic phenomena, kinda like the "sprites" and "jets" often seen on the tops of thunderstorms. Only with these things, there's no storm around, they are near the ground, it's broad daylight, etc. Some folks think they're associated with faults in the Earth's crust, but nobody really knows. Anyway, the float along all glowing and shiny, sometimes changing their sizes, shapes, and colors, but sometimes not. Then they usually shoot straight up and/or just disappear, like whatever was holding them in equilibrium suddenly failed.
