Been documenting this for years and the pattern is undeniable once you start paying attention. I've had it happen in three different locations including a Victorian mill conversion near me that I've visited probably a dozen times now. You walk in, lights are steady, the moment you start moving through the space it follows. Not every light, just specific ones.
My working theory is its not random electrical fault. Buildings this old have had decades of human emotion baked into the walls and I think certain presences are drawn to the electromagnetic signature we put out as living beings. We're basically walking batteries from their perspective.
Has anyone tried an EMF meter alongside this to see if the readings spike in the same rooms? I've got some decent data from the mill but I'd love to compare notes with someone who's had the same experience in a different type of building. Churches especially interest me, loads of reports of this happening in old parish churches round South Yorkshire.
What triggers it for you lot - does it happen the moment you enter or does it take a few minutes?
