Went there about three years back with a couple of lads from my local paranormal group. The EMF readings in the east wing were all over the place, nothing we could pin to wiring or external interference. But more than that - and this is the thing that sticks with me - there was a pressure sensation around the old treatment rooms. Not everyone felt it, only two of us out of five.
What did you pick up on specifically? Because Briarwood has a reputation for very localised effects rather than building-wide activity, which is unusual and honestly makes it more interesting from a research standpoint.
I'd love to compare notes if you got any photos or readings from the visit. I do a fair bit of paranormal photography and certain locations produce anomalies in the same spots consistently, Briarwood being one of them. Worth cross-referencing what different groups capture over time.
