Never been to Waverly Hills myself but it's been on my list for ages. Cold spots near staircases are so common in these investigations and I genuinely think theres something to it - not just draughts from the structure.
From everything I've read the fifth floor and the body chute get all the attention but accounts of the staircase area keep cropping up in older reports too. Did it feel localised? Like a specific patch you could step in and out of, or was it more spread across the whole area? That detail matters a lot to me when I'm trying to rule out mundane explanations.
Anyone who was actually there - did you get any readings on a thermal camera or was it strictly a physical sensation? Would love to hear more from people who've done overnights there.
