I know it is probably my pre-conscious processor being overloaded or something, but after I photoread and went to sleep right after, when I had my eyes closed they would move involuntarily, back and forth as if I was asleep already!
I didn't even realize it was happening at first. but then I felt my eyes and they were quickly jumping back and forth. Has this happened to anyone before?
I think I photoread too much at once of a huge technical book.
