That feeling of not being able to stop thinking about it is something a lot of people describe after a sighting. Like your brain just keeps looping back to it no matter what you try to do. I've spoken to a fair few witnesses over the years and that mental replay is almost universal.
Would really help to know more details though. How long did it hover for? Was there any sound at all, or was the silence part of what made it weird? A lot of the cases I find most credible are the ones where people specifically note the absence of sound rather than any obvious lights or movement.
Also whereabouts in the country are you? Not asking for your exact location obviously, just curious whether this matches anything else thats been reported in the area recently. There have been a cluster of reports from the north west over the past few months that haven't really been explained.
