How would you make sense of a figure seen through a window?

I’d start with the viewing conditions, not the identity of the figure. A street view through glass can combine reflections, objects inside the room, and changes in light. A large mirror nearby could add another layer of confusing shapes. Those are possibilities, not proof of what was seen.

The lights going out at the same moment would make the scene feel especially connected, but timing alone can’t tell us whether one caused the other.

If someone wanted to check it out, I’d write down the location, time, weather, how long the view lasted, and where they were standing. Then check from a public spot in daylight, without entering the building, and see whether the window, mirror, and room layout could produce similar shapes. A second independent observer would help too.

Without a clear recording or another witness, the details may stay uncertain. That doesn’t mean the person made it up. It just limits what anyone can conclude.

I wouldn’t rush to label it paranormal, but I also wouldn’t pretend a description alone explains it. Low light, distance, and a startling change in what someone thinks they’re seeing can all matter. If the experience happened during a tiring stretch of travel, that could be worth noting too, though it wouldn’t establish a cause.

Best answer might simply be that it was vivid and unsettling, while the exact explanation remains open.
