Anyone else had weird experiences at the old Briar Hill sanatorium in western PA?

Never been to that specific site but western PA in general has this strange energy I can't quite put my finger on. Lots of old industrial history, lots of grief baked into the land if that makes sense.

What kind of experiences are we talking? Because with abandoned sanatoriums there's usually two camps - people reporting classic residual stuff like sounds and shadows, and then occasionally you get the more unsettling intelligent responses. The kind where something clearly knows you're there.

I had a similar visit to an old Victorian asylum in Somerset a few years back and the photography alone was worth it. Got some genuinely odd light anomalies in the east wing that I still havent fully explained to my satisfaction.

Would love to hear what others have picked up at Briar Hill. Any EVP work done there? And has anyone tried going in the early hours rather than evening - in my experience the 2am to 4am window tends to produce more activity, or at least more that gets captured on equipment.

@IslaOrb that "grief baked into the land" thing is actually a real concept - residual hauntings are basically the same idea, traumatic energy imprinted on a location rather than an actual conscious entity hanging about.

Western PA had a brutal industrial period, mines, steel works, loads of workplace deaths that never got properly acknowledged. Sanatoriums on top of that is just stacking misery on misery really. Some researchers reckon places like that accumulate activity over decades rather than it being tied to one specific event or person. Never been to Briar Hill myself but Edinburgh's got its own version of that same heavy atmosphere in certain spots and you absolutely feel the difference walking into some buildings versus others.

Would love to hear from anyone who's actually done a walkthrough there.
