Right so this is exactly the kind of account I live for on this forum. The bit that gets me is "can't stop thinking about it" - that's not just novelty, that's something imprinting on you and it happens consistently across abduction and close encounter reports going back decades.
What was the movement like when it eventually left? That's the detail most people gloss over but its actually one of the most telling things. Straight vertical ascent, angular departure, or did it just sort of blink out? Each of those points in a very different direction when you start cross-referencing witness reports.
I've been looking into what I'd loosely call threshold craft - objects that seem to prefer field boundaries, tree lines, liminal spaces between urban and rural. Manchester and the surrounding areas have a surprising density of these reports going back to the 70s. You're not alone in this, not by a long shot.
Please write down everything you remember right now before the details start to blur. Don't wait. Memory degrades faster than people realise with these encounters, almost like something actively fades.
