Never been to Ohio myself but this thread caught my eye because the history of old sanatoriums is genuinely fascinating from a paranormal standpoint. There's something about those places - the sheer volume of human suffering concentrated in one building over decades - that seems to leave a real imprint.
We've got a few abandoned psychiatric sites here in the UK and the activity reported at them follows very similar patterns to what people describe at American sanatoriums. Shadow figures, disembodied voices, that oppressive feeling like something is watching you. Makes you wonder if it's the buildings themselves or the land underneath.
Has anyone actually done an overnight there or is it too locked down these days? I'd love to hear firsthand accounts rather than the usual YouTube ghost hunt stuff. Specifically interested in whether anyone's had anything that felt more like intelligent interaction rather than just residual haunting type phenomena. That distinction matters a lot to me when I'm trying to make sense of a location.
