Went to Millbrook last Saturday with my usual kit - Zoom H5 recorder and a cheap IR camera I picked up off eBay - and yes, absolutely felt watched the entire time I was in the east wing corridor. That particular stretch near the old treatment rooms gave me a persistent cold sensation that wasn't down to draughts, I checked carefully.
What's interesting is I pulled the audio back and around the 47-minute mark there's something that sounds distinctly like a low exhale or possibly a word. Still running it through Audacity to clean it up. I'll post the clip once I've isolated it properly.
A few things I noticed specifically:
The temperature in room 14 dropped noticeably compared to the adjacent rooms, My camera kept struggling to focus in the main stairwell, which it normally handles fine, Strong smell of something medicinal near the basement entrance that nobody else in our group could identify
The watched feeling was strongest on the second floor landing, which apparently was the nurses' station historically. That detail came up after the visit when I looked into the building's records, which I always prefer to do retroactively so I'm not leading myself with expectations.
Was anyone else there over the weekend? Genuinely curious whether other groups experienced anything in the same areas or whether our location within the building made a difference. Would be particularly interested if anyone else captured audio - comparing EVP sessions from different parts of the building at roughly the same time could be really useful for building a proper picture of activity patterns.
