Driving in my car, spotted a ufo that changed shape and had flashing colored lights on it

I was driving back to my hotel after I had been at a wedding all day. It was late, approximately 10:40pm. I was driving in my car on a main road in the city I was staying in and some flashing lights caught my eye through the upper left corner of my windshield. I looked up and out, expecting to see an airplane. For a second I thought it was a plane. The craft seemed low in the sky, like about where a commercial jet would fly, or maybe even a bit lower like when a plane will come in to land. My mind was having trouble processing what I was seeing and it happened so quickly, but I initially saw a triangle type object. There was lights blinking on it sporadically, green/red and possibly white. It wasn’t blinking off and on like you’d expect on an airplane, it was more erratic, like a lot were going on and off at the same time. Then it seemed to morph into a spherical shape rotating in the sky still flashing with the sporadic colorful lights. And then it was just gone. It was there and then it wasn’t. I didn’t see it zoom away. It was just there and then not. It was so bizarre. I kept looking out my car windshield the rest of the drive and I couldn’t see anything again. I was only a few blocks from my hotel so when I parked I scanned the night sky and I saw nothing out of the ordinary. I hesitate to even share this account since it was so quick and I was by myself in my car. I barely had time to process what had occurred, my whole sighting happened in probably 30 seconds or less. Most likely less, it’s hard to gauge time. I’m hoping maybe someone else saw something strange around that timeframe that could potentially validate my sighting as well. The night was clear, and pretty warm out. I don’t remember seeing any clouds that could obscure my vision. I do not believe this was an airplane or a weird reflection in my window. Nor is this a hoax or fabrication. It was just a very quick and very weird event.
(You don’t have to include this in the report but when I submitted my account the first time I didn’t leave any contact info, I’m sorry about that, I just really wish to remain anonymous. If you need more details, feel free to email me, but what I have listed above is the most accurate details of my sighting that I can remember.)
