Yeah this is something I've been thinking about for a while actually. My mate's house in Crewe, every single photo taken in the hallway near the stairs comes out with orbs. Living room, kitchen, nowhere else. Just that one spot.
I've seen people write it off as dust particles catching the flash but that doesn't explain why the dust would only gather in one specific corridor and not literally anywhere else in the same house. Doesn't add up to me.
My theory is it's got something to do with specific locations having residual energy rather than orbs just floating around freely. Like certain spots act as a kind of anchor point. Would be interesting to know if anyone's cross-referenced orb hotspots with like, old floor plans or historical records of what happened in those rooms. Anyone actually tried that?
