Living near Rendlesham forest you get a bit obsessed with tracking this stuff and yeah, I've noticed a pattern that I think gets overlooked a lot. In my experience the incidents cluster around new moon and also the few days either side of a full moon, but for different reasons I think. New moon is interesting because there's basically no natural light interference and I wonder if that matters for whatever mechanism is involved. Full moon adjacent stuff feels different in character, harder to explain.
I've been cross-referencing my own field notes with reported cases going back about fifteen years and the correlation isn't perfect but its definitely not random either. Would be really interested to know if anyone else has been keeping proper records rather than just going off memory, because memory is obviously unreliable when you're talking about missing time specifically. The whole point is you don't remember it properly.
What phases are people finding most active? And are we talking minutes or hours in terms of the gaps?
