Pulsating light doing 90 turns and zig zags before shooting off then disappearing

Driving to work I noticed what I thought was an airplane until I noticed no aviation lights, just a pulsating white light like a star. I noticed it between 2 stars before it started moving. It would get very bright then real dim. I slowed down to watch it then noticed it started moving. Very slowly at first, then gaining speed. I started watching as it started to make a couple sharp 90° turns and I knew it wasn't an airplane. It took off very fast then slowed down and done a couple zig zag maneuvers before it stopped. Once it stopped it sat for 2-3 seconds before just disappearing but i never seen it fly off, it just vanished. I didn't have time to get my phone to take any pictures or videos. It was only 1 craft that I noticed. I've never had any experience like this before. I'm an avid stargazer and have no reports of any mental health issues in my family. I'm a healthy 29 year old male with no medical or mental health issues. There has been 1 other UFO sighting in my same small town back in the 1980's that I know of. Very strange sighting and have seen a couple stories of the exact same lights in other places.
