Wasn't there last weekend but did the overnight at Waverly back in 2019 and the experience has stuck with me since. The fifth floor is where it gets uncomfortable, not in a dramatic way, more like a pressure change and that particular silence that doesn't feel like normal silence if that makes any sense.
What I noticed photographically was interesting - kept getting this thin vertical distortion in shots on the body chute corridor, consistent across three different exposures. Not lens flare, wrong conditions for that. Could be dust but the pattern was too regular.
What specifically did you feel and whereabouts in the building? The room 502 area gets a lot of attention but in my experience the real activity tends to cluster in less talked about spots. Would be useful to compare notes if you can be specific about location and timing.
