Moved erratically in clockwise or counterclockwise pattern from my frame of reference

I was having a late night snack as I watched the movie Pan's labyrinth in my bedroom when I noticed one of the brightest white stars I have ever seen from my window that was facing west. Naturally I walked towards my window and took a moment to admire the beauty of the bright star when it suddenly began moving erratically in a clockwise or counterclockwise direction (don't recall exactly which). I was in complete shock and awe so I slowly moved backwards to reach my phone and record the sighting but as I touched my phone it instantaneously took off North as if it was a shooting star. Even though I know I shouldn't make assumptions about something as unexplainable as this sighting it felt as though it was trying to crudely communicate with its erratic movements. I'm an engineering major so of course immediately after the sighting I went straight to google and typed in possible objects mistaken for UFOs to try and come up with a plausible explanation for what I saw like ball lighting, atmospheric turbulence, or rocket testing. Whatever I saw that night I can't explain, it seemed to not operate under classical mechanics like we do and I'm still trying to process it. Thank you for taking the time to read my experience and feel free to email me if any more info is needed.
