Mate that feeling of "I can't stop thinking about it" is basically the universe's way of telling you it was real, your brain knows what it saw even if the rest of you isn't ready to accept it yet.
What colour was the light? That's always the first thing I ask because in my experience the colour tells you more than the shape does. Orange is almost always something mundane but pure white or that weird blue-white tends to be the stuff that ends up on this forum for a reason.
Also how long did it hover before it moved or disappeared? Duration is massively underreported and it matters a lot when you're trying to rule things out. Had a similar one over a field near Dalkeith about three years back, just sat there completely silent for what felt like forever then gone in half a second, no sound, no trail. Still gets me thinking. Post as much detail as you can remember, the more the better.
