Moving light thought to be a star at first

It was a clear night. I was sitting on my porch just stargazing. Movement to the left of a star that I was looking at caught my eye. It looked like another star but it was moving! I thought my eyes were playing tricks on me so I looked away to let my eyes readjust and then looked back up at it. It was still there and still moving. It was going on a downward but also western direction.
The speed of it moving was faster than what I’ve been seeing planes move at but it was also a jumpy kind of movement, it wasn’t smooth in just one straight line. I really tried telling myself it was a plane or a “moving” star which is probably not even a thing. I noticed that it began getting brighter and appeared to be coming in closer. It was very very high  in the sky but that’s what it looked like, like it was coming closer towards me. That, coupled with the fact that it was getting brighter frightened me and I pulled out my phone to record just in case. It was only a few seconds later that it then appeared to get smaller or further away again and dimmer until it dimmed all the way out or disappeared in a way.
I don’t record it all because I wanted to to see it with my own eyes instead of looking at it on the phone camera .It’s almost as if me recording sacred it away. It was weird.
