Wasn't there myself but I've been following this location for years and Waverly is one of those places where I genuinely believe the residual energy has built up to an extraordinary degree. Hundreds of deaths over decades, all that suffering - it doesn't just disappear. It imprints.
What exactly did you feel? Was it more of a pressure sensation or something you'd describe as a presence? I ask because there's a known ley convergence in that region of Kentucky that some researchers think amplifies whatever is already there. I've read accounts going back to the 80s of people experiencing time slip episodes on the upper floors specifically.
Would love to hear more detail from anyone who was on the tour. Were you in the body chute at any point? That corridor generates some of the most consistent reports I've ever come across and I'd like to compare notes with fresh eyewitnesses.
