Anyone else experienced cold spots that move around the room on their own?

Had this exact thing happen in my old cottage in Somerset - pre-renovation, when the place still had all its original Victorian bones. You could track it almost like a slow-moving object. Sat in the corner near the fireplace, then drifted - and I mean drifted, not jumped - across to the doorway over about twenty minutes.

What made it compelling rather than dismissable was that I had a FLIR thermal camera running at the time. The cold patch showed up clearly on the display, distinct edges, moving independently of any draught source. I'd already ruled out the obvious culprits - windows sealed, no through-floor vents active.

The temperature differential was roughly 4-5°C cooler than the ambient reading on my Govee sensors dotted around the room.

What I find fascinating is the intentionality of it. Random thermal convection doesn't behave that way. Cold air sinks and pools - it doesn't cruise at chest height in a deliberate arc toward a doorway.

I've cross-referenced this with several black-eyed children encounter reports I've been cataloguing, where witnesses describe a sudden localised cold that seems to precede the entity before visual contact. Almost like a herald effect.

Anyone else noticed that - the cold arriving before something else does?

Would love to know if others have caught moving cold spots on thermal imaging specifically, rather than just felt them. Subjective sensation is one thing, but having it on camera changes the conversation entirely.

Not really my area - I'm more of a Bigfoot person - but I've done enough overnight field work in the Oregon wilderness to know that unexplained cold spots are genuinely weird.

Out in the forest, you can usually blame cold air pooling in topographic low points, or thermal drafts off water. But in an enclosed Victorian structure like @RetiredFreelanceWebDesigner describes? That drainage explanation falls apart pretty quickly.

The movement is the key detail here. Static cold spots have mundane explanations. Moving ones are harder to dismiss.

If you ever document this again, I'd recommend grabbing something like a FLIR thermal camera - even the cheaper smartphone attachments show thermal anomalies really clearly. Tracking the actual temperature gradient as it moves would tell you a lot about whether there's airflow involved or something genuinely stranger happening.

Has anyone actually captured consistent thermal footage of this phenomenon?

Cold spots that move are a different beast entirely from static ones. Static cold spots I'm fairly sceptical about - usually draughts, thermal bridging, that sort of thing. But a travelling cold spot is harder to explain away mechanically.

I've logged something similar in a farmhouse near Penrith. Used a Flir thermal camera alongside three digital thermometers placed around the room. The anomaly tracked consistently across all three readings in sequence, roughly 90 seconds apart. That's not a draught pattern - draughts don't queue politely between sensors.

@RetiredFreelanceWebDesigner - did you notice any correlation with time of day? Mine consistently appeared between 11pm and 2am, which rules out solar heating/cooling cycles as a cause.

My working theory with poltergeist-adjacent phenomena is that the cold isn't the thing itself, more like a byproduct of something drawing energy. But I'll admit that's speculation rather than data.
