UFO Sighting in New Zealand [I Saw a Ufo]

I just saw a UFO... I was crossing a bridge at night in a forest. I think that's why I saw it. There were no street lights where I was. It was very dark and being on a bridge, there were no trees blocking my view of the clear night sky. This aircraft looked like a pale ghostly white star with a soft white glow around it stretching quite far and concentrated in the direction it was moving. The whole thing looked very ethereal. It was moving in a way that I've never seen any human aircraft move. It was sometimes erratic. It was graceful. It looked alive. I was so humbled by what I just saw.
