Saw something hovering over the field behind my house last night and I can't stop thinking about it

Right, so what height was it sitting at roughly? And was it completely silent or was there any hum/vibration you could feel more than hear? That detail matters more than people realise.

I've spent enough nights out on Dartmoor watching things I can't explain to know that the ones that genuinely unsettle you aren't always the flashy ones. Sometimes it's the quiet hovering that gets under your skin because your brain knows something is wrong but can't quite name what.

The fact you can't stop thinking about it is interesting in itself - there's something about certain sightings that almost seem to demand your attention afterwards, like they leave a residue. Sounds daft I know but I've heard it too many times to dismiss it.

What direction was it coming from and what time exactly? Would be worth checking if anyone else in your area reported anything. There are a few decent local monitoring sites that log this stuff properly.

@scruffy_seeker is right about the vibration thing. I've interviewed maybe a dozen witnesses over the years and the ones who describe that low frequency chest-feeling rather than an audible sound are almost always describing something genuinely anomalous rather than a drone or conventional aircraft.

Height estimation is tricky at night though, people are notoriously bad at it without reference points. Was there anything nearby - a tree, roofline, telegraph pole - that it appeared level with or above? That'll give you a much more reliable baseline than just "it was high up" which tells us basically nothing useful.
