Yeah I noticed it straight away, stopped me dead. It wasn't just a slight drop either, it was like walking into a freezer compared to the rest of the corridor. My mate thought I was overreacting but you could literally see his breath when he stepped into it.
What got me was how localised it was. Two steps back and it was gone, two steps forward and you're right in it again. Doesn't feel like a draft or air con to me, the boundaries were too sharp for that.
Did anyone pick up anything else near there - sounds, EMF spikes, anything? I only had a basic thermometer with me so I didn't get a proper reading unfortunately. Would love to know if others experienced the same spot or if it moves around at all, because I've read a few accounts where people mention cold spots shifting locations in the same building over time.
