Blimey, this is exactly the sort of thing that keeps me up at night and I don't even mean that metaphorically. What colour would you say it was? That detail matters more than people realise.
I had something similar back in 2019, standing in my back garden in Salisbury just after midnight. Hovered for maybe three or four minutes then just went. No sound at all, which is the bit that really got under my skin.
The Men in Black angle is worth considering too - did you notice any unusual visitors or strange vehicles in your street in the days after? That's often how it escalates and I'd genuinely like to know if there's a pattern here.
How long did it hover for before it moved off?
