I have seen something yes, my brother and I were night fishing at wicksteed park in about 1992 and in the middle of the night there was this thing that appeared and hovered above the lake, no real lights just a slight glow to it, and it was silent. I was staring then my brother noticed it, both still talk about it to this day.
However, we were burning plastic Milk crates at the time so the inhaling those fumes may have had something to do with it 🤣.
