Wasn't there last weekend but I did the overnight tour at Waverly back in 2019 and that place is genuinely something else. The body chute corridor was where it hit me hardest - like this sudden pressure drop and a real heaviness in the chest that I couldn't shake for a good 20 minutes after leaving that section. My mate who came with me felt nothing, which is usually how it goes.
What specifically happened to you? Was it in the 4th floor area or lower down? I've read accounts from multiple people who all report similar physical sensations in the same corridors which is the part that interests me most. Collective experience in the same location points to something environmental or residual rather than just suggestibility imo.
Also curious whether any of you were running any equipment. I'd love to see temp readings from that weekend if anyone has them.
