I found a book and started reading it . The words kept changing around and moving out of order so that I could n't read it , but I still could sort of understand what the words were saying . My brain knew that I could read , so it made me read in the dream , but my active logic centre knew that the words were nonsense , which was interesting . Then I decided that , if this was a dream , I could most definitely fly .

Question: Why is the narrator having some trouble reading ?
Answer: The book is written in small font .The book is in another language .None of the above choices .The words are changing .
