You know Annah, I recall reading a paper about that many years ago. What caught my eye was a description of the way some people precieve motion as a sequence of abrupt points. If you think of a ball, flying past, some people don't actually see it as a continual sweep, rather as a series of abrupt, if rather blurry. points.
Apparently, the syndrome was shown to be more acute when the subject is under any sort of stress.
I appreciate this is not quite the same as your experience, but suggests that disturbances of visual preception of these types, may have a genetic element. That is, innate, rather than inherited, if you follow the difference?
I did think about following it up, at the time, to check if there were any links between altered preception and to other conditions, colour blindness for example. I know, for example, that colour blind people, especially those with some types, tend to have good dusk vision, for example. (Humans generally have terrible dusk vision).
Sadly, other priorities arose.
