I've learned why I struggle to read books and other documents while dreaming at night.
Lately, to figure out why, I've decided in my dreams to pay attention to the individual letters.
It turns out all the words are not really words after all. Just a cluster of random letters.
I guess my sleeping brain just isn't going to go through all the work of coming up with brilliant text for me to read in a dream.
I'll have to stick to reading books in real life while I'm awake.
