Mate I stood on that staircase for a good ten minutes and it was absolutely freezing in one specific spot, like stepping into a cool room but there's no aircon anywhere near it. Did a quick thermal reading and got a 4 degree drop in about a half metre radius, no obvious draughts, no vents, nothing structural that would explain it.
What got me more was that it didn't move. Most cold spots I've investigated shift around a bit as air circulates but this one just sat there. Been to a lot of locations across Australia and the US and thats probably the most consistent anomaly I've personally documented in years.
Anyone else do thermal imaging there? Would love to compare readings because I'm not ready to slap a "definitely haunted" label on it but I'm also not going to pretend it was nothing. What did you all pick up?
