Wasn't there myself but I've been reading about Waverly Hills for years and always wanted to go. That place has a documented history of death that goes way beyond just "spooky atmosphere" - we're talking thousands of tuberculosis patients over decades, and there's actual research suggesting locations with high emotional trauma can leave some kind of residual imprint. Whether you call that a haunting or something else is another debate entirely.
What exactly did you feel? And whereabouts in the building - the body chute area, the upper floors? Because from what I've read the reports aren't evenly distributed across the whole site, certain corridors come up again and again in accounts from completely unrelated visitors who had no prior knowledge of the specific locations.
I'm sceptical of a lot of ghost tour stuff if I'm honest, feels like theatre half the time, but Waverly Hills is one of the few locations where I'd take the accounts a bit more seriously given teh sheer volume of independent reports over the years.
