AAHHH I NEED MORE!!!
The idea of a tall woman apparition being reported by multiple people talking about some sketchy Car Boot Sale, and then one of those people just says a nonsensical phrase and never stops walking after that-
its so eerie is such a wonderful way.
In one of my yet to be written stories, the residents of the town catch this mysterious illness where they stay stuck staring up at the sky, unmoving, for days, until one day they break out of the trance but instead begin running. Some run off cliffs, others climb trees to be as close to the cloud as they can and falling off accidentally leading to their death.
Is this lady real? Like is she an actual human in your world? Or an anomaly that only a few characters ever encounter, and those that do seem to go crazy.
AND WHAT'S THE RECTANGULARABOUT?
