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?
Yeah, at least I can remember getting a phone call and looking at my phone and reading the caller ID. I don't think it comes up much though.
The fact that I read the caller ID and thought "oh yeah, that's my 4 year old daughter's lawyer" when I saw the name, that should have been a clue I was dreaming.
