We get a lot of planes and helicopters that go by but this one was different. It was too fast and too quiet

I couldn’t sleep and for some odd reason I felt the need to look out my bedroom window. I thought I saw another low flying plane or helicopter of some sort. But it was moving so much more fluid and faster than the plane in the sky behind it. It had rotating lights on the bottom that changed colors and moved fast. I tried taking pictures but it was like my phone couldn’t adjust enough. It moved forward and backwards towards my location slightly rotating from side to side. It lasted for about 30 minutes. I kept my eyes on it the entire time watching the lights change from green to blue, red, yellow, white. I ended up just laying down in bed after each one of my pictures wouldn’t come out clear
