As I was reading I felt like my 'visibility' at any given time was only like 1-1.5 pages into the past. Sometimes less. Meaning the context for what I was reading, my understanding, went back about that far. So I basically experienced it as "word soup" with some identifiable parts in like the last page, that I could sort-of kind-of divine a narrative from, somewhat.
