I was driving home from work in the evening on February 24, and I was only a minute or two away from home (rural back-road in wooded area) when I spotted a very bright, single white light that looked like a star in the sky.It caught my eye because it was moving and changing directions. Initially, I thought it was a helicopter because that's how it behaved. It was very high in the sky when I first saw it (not good with measurements - it was much higher than the crest of the mountain behind it), but as I got closer to the stop sign at the end of the street, it descended and started to move in the direction that I was about to turn. I watched it moving farther away until I pulled into my driveway, and when I stepped out of my car, I noticed it make a U-turn and travel back towards me - so I quickly turned on my camera phone and started to record as it moved in a straight path directly over my head. This is when I realized that it was not a helicopter, because it was flying very low (much lower than it appears in the video) and it was completely silent.I stopped recording when I lost sight of it, but as I prepared to walk from the driveway toward my house, I saw it coming back in the opposite direction again, but this time it was moving behind the treeline across from me, and I lost sight of it again eventually. The entire event lasted approximately 15 minutes, and this light had changed direction a total of 3 times as I watched. I considered the possibility that this could have been some type of drone, but I have witnessed the same lights several times in the past - and on many of those occasions, they blended in with the stars very high in the sky, and they were often stationary before moving (as if intentionally camouflaged with the stars).
