Anyone else noticed shadow figures always seem to appear in doorways specifically?

Genuinely one of the things that keeps me up at night (figuratively and sometimes literally tbh).

I've been documenting shadow figure reports for about three years now and the doorway correlation is staggering. My running spreadsheet has 340-odd cases and roughly 68% specifically mention a threshold - doorways, archways, the top of staircases. Rarely just standing in the middle of a room.

My theory? Thresholds are liminal spaces. Every culture going back thousands of years treated doorways as sacred boundaries between states of being. The Romans had Janus literally for this reason. Maybe whatever these things are, they're drawn to - or can only manifest at - points of transition.

The sceptic answer is obviously pareidolia plus the fact that doorways naturally frame a human-shaped silhouette, so your brain fills in the gaps. Fine, sure. Except that doesn't explain the movement reports, or why they consistently retreat back through the doorway rather than just disappearing on the spot.

I've had one personal experience in an old farmhouse in the Fens - classic tall, featureless figure, standing in the bedroom doorway for maybe four seconds before it was just... gone. No audio, no temperature drop, nothing on the thermal camera I had running. Infuriating.

Anyone else noticed whether the figures seem aware of being observed? That's the detail I keep coming back to. Most witnesses describe a sense of being deliberately watched before the figure moves.

What are your experiences? Particularly interested if anyone's had one appear somewhere other than a threshold.

The doorway thing is interesting but I'd push back slightly on treating it as a given - there's a massive selection bias issue here because doorways are literally where your eyes naturally go in any room. We scan exits instinctively, so we're primed to notice anomalies there more than say, a corner. That said I've been reading about threshold symbolism across cultures and the idea that liminal spaces (physical transitions between rooms) might somehow correspond to dimensional or energetic boundaries does keep coming up in a way that's hard to dismiss entirely. Whether thats the explanation or just confirmation bias dressing itself up as pattern recognition, I genuinely can't say yet. Would be more convinced if someone had done controlled documentation counting shadow figure sightings by location within a room rather than just recording the doorway ones because they felt significant.
