Never been to Waverly Hills myself - it's a bit of a trek from Cumbria - but I've followed it closely for years. The sheer volume of documented cases coming out of that place is hard to dismiss, even if you're sceptical.
What gets me is the consistency of reports. You've got multiple independent groups picking up similar EVP signatures in the same corridors, same rooms. That's not nothing. The body chute alone has some genuinely unsettling data attached to it.
I'm primarily a SHC researcher so I'm more desk-based than field-based, but I do run a basic investigation setup - K-II meter, a Zoom H5 for audio capture, full-spectrum cam. Nothing fancy. Waverly Hills is on my list though, mainly because the atmospheric conditions in an old TB sanatorium are interesting from an environmental standpoint. High residual moisture, degraded materials, decades of intense human suffering concentrated in one building. If there's any location where stone tape theory might actually hold some weight, it's probably there.
Anyone who's actually done the overnight tour - what surprised you most? Was it the fourth floor that delivered, or is the body chute as active as people claim? Curious whether the experiences tend to be visual or more audio-based.
