Been driving me nuts all morning reading this. What colour was the light? That detail matters more than people realise. There's a lake about 40 miles east of me here in Oregon where people have been reporting hovering objects going back decades, and in almost every single case the witnesses describe either orange or a kind of blue-white that doesn't behave like any normal light source. It doesn't flicker, doesn't strobe, just holds steady and then moves in a way that aircraft simply cannot replicate.
The lake connection is something I've been looking into for a while. Water seems to draw these things. I don't know if its electromagnetic, geological, or something else entirely but the pattern is way too consistent to ignore.
Did it make any sound? And roughly how long did you observe it before it moved off? Really need those specifics if we're going to narrow down what you actually saw.
