I ask because it's considered common knowledge that you can't but I regularly have dreams where I continue books I'm reading irl (they usually devolve into naritive nonsense over time and then sometimes to blank pages, but the actual text is definitely deciferable), text messages, computer screens, and road signs, in both lucid and regular dreams. Am I the odd man out or is it actually just something people say?
I have not heard of this as "common knowledge." I can't particularly remember reading in a dream, but I don't remember much about past dreams. Is there a source here, or is it just something you've kinda heard a few times?
