> But the best way for me to know I'm in a dream is when I am reading some text. Texts are inconsistent and when I reread a sentence it might be completely changed.

This is exactly what happened to me just last night. I was able to read a page from a book, which was visually perfect, as if I was reading a real book. However, once I read it and diverted my gaze, then looked back to it, some of the words had changed (not all). This made me realize I was in a dream.
