Never been to Millbrook personally - I'm based over in Cumbria so a bit far for a weekend trip lol. But I've been following reports from that place for a while now and some of the accounts are genuinely interesting. The shadow figure stuff near the old east wing keeps coming up from different people who clearly haven't talked to each other beforehand, which is the kind of thing that makes me sit up a bit.
I'm usually the first person in any group to say "yeah that was just a tree" or whatever, but when you get consistent independent reports of the same thing it's harder to dismiss.
Anyone actually done a proper overnight there with decent equipment? Would love to know what the EMF readings were like in those basement corridors everyone keeps mentioning. Has anyone managed to get audio that wasn't just building noise?
