Didn't go last Halloween but I've been past Beckford Mill a few times over the years and that place has a proper odd atmosphere even in daylight. My mate and I stopped there back in maybe 2019 and we both clocked something moving near the old wheel housing, dark shape, no real form to it. Wrote it off at the time but reading this thread now I'm not so sure.
Are we talking full shadow figures or more like peripheral stuff that disappears when you look directly at it? Because in my experience those are two quite different things and the peripheral ones worry me more to be honest. Could be connected to the ley line that runs through that part of Dorset, there's definitely something running through that valley.
Anyone done a proper vigil there or is it all just passing sightings?
