Wasn't there last weekend but I did a night there about two years back and honestly it messed me up a bit. The body chute was the worst for me - just this horrible heavy feeling like something pressing on your chest the whole time you're in there. My mate thought I was being dramatic but her torch kept cutting out every time we went near room 502 which is a bit hard to explain away.
What did you actually feel? Like was it a physical thing or more of a general dread atmosphere? Waverly is one of those places where I genuinely cant tell if its the history getting into your head or something more. Would love to hear what others picked up on - especially if anyone was doing any equipment runs at the time.
