An orb or some kind of light dancing in and out of one cloud bouncing all around it.

I was leaving my house at 530am, i had just pulled out of my driveway, reaching the end of the street at my cul de sac, when i stopped to let a runner cross the street in front of me, otherwise i would have kept going as i usually would, and as i waited i looked up at the very dark barely blue pre sunrise sky and noticed a smallish cloud oddly lit up around its edges, no other clouds around were that way, this was a mostly clear morning but for two or three little clouds, that was when i first noticed this odd light dancing in and out of that cloud and zooming all around it playfully, i could even see it bouncing around inside the cloud quickly changing direction and making all sorts of erratic patterns. I watched it play around and in and out of that cloud for about a minute, when i decide to drive off somewhat perplexed… i had to catch the train to work. I get to the train station, i get onboard, and as the train is pulling off, i look to the sky in the direction i saw the dancing light, when i noticed the cloud it was playing in had a lit up silver lining, and what looked like trails of condensation in the sky all around that cloud in all sorts of odd patterns… i realized immediately that they were left by whatever was up there playing in that cloud. There were no planes in the sky yet as it was still too early for commercial flights, no helicopters, nothing. The sun hadn’t even risen yet, and no sight of the light, it was gone. In summary the light behaved like a playful hummingbird completely uninhibited and frivolous and unthreatened in anyway. What made it even more bizarre is that i live less than 10 miles from the capital in DC, and nothing flys like that around here, not even military planes. This was unique, and oh yes one last thing gravity mattered not to it, it moved in any direction effortlessly.
