I can read perfectly well in my dreams. Like the letters are sharp, clear, and perfectly legible. The problem is when I look away from something and then look back the text usually changes. Once I lucid dreamed because I walked past a street sign, realized it was the name of a different street than the one I was on, looked back and say the other side of the sign read a third street name, walked back to the other side and saw a fourth name. I decided I should take this opportunity and be cliche and try to fly. I just kept going up till it was really bright and I woke up. Mostly now I just recognize I'm in a dream and go along for the ride, but better able to remember it.
