Mates, cold spots near staircases are basically the paranormal equivalent of a "Welcome". Mat - every haunted gaff's got one.
That said, the Lemp Mansion is genuinely on another level. The sheer density of tragic history in that building creates conditions I'd expect to produce consistent, repeatable anomalies rather than your one-off dramatic nonsense. When you've got multiple suicides on the same staircase, the residual energy argument starts looking less like wishful thinking and more like a reasonable hypothesis.
From my own investigations around Leeds and beyond, I've noticed cold spots that correlate with documented EMF fluctuations - running a Mel-8704 alongside a decent K-II tends to paint a more complete picture than temperature readings alone. Has anyone actually done a proper multi-instrument sweep of that staircase area, or is it mostly anecdotal at this point?
What I'd love to know is whether the cold spot maintains a consistent location, because a fixed anomaly is far more interesting than a wandering one. Moving cold spots can usually be chalked up to draughts, dodgy insulation, or someone leaving a window open because they panicked at a shadow.
A stationary, reproducible cold spot though? Now we're talking.
Anyone been recently with proper kit rather than just a phone app and pure optimism? Share your data - actual readings preferred, dramatic personal testimonies also accepted because frankly they're more entertaining anyway.
