Comet? Meteor? UFO? Space Junk???

So I am at work Wednesday night, and head outside to take the trash out. And I see these strange lights moving across the sky!  At first I figure I must be hallucinating, because it looked like fireworks, all glittery, gold, green, and blue...but moving sideways. I stood there speechless, watching this amazing sight, then realizing I could be watching history, decided I needed a second set of eyes to confirm I wasn't going crazy!  Is this for real? A comet? A meteor shower? UFO?

This brilliant display lasted for about 45 seconds, traveling from west to east before it left our view. I then grabbed my phone and reached out on Facebook to see if anyone else had witnessed this. I found that several in my area had, but no one had an explanation. A bit later, after I got home, reports were coming in that it was some sort of "space junk", which has now been confirmed to be the Chinese CZ-7 R/B Rocket Booster breaking up after re-entry into the atmosphere. Still, an incredible event I will not forget any time soon, as I wonder what inspired me to be outside at that exact moment.
