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've debugged code in my dreams before, so I think dream reading is something that varies from person to person. Also I only have minor issues using computers and phones in dreams, like my typing sucks but it's not too difficult, keyboard shortcuts don't always do what I expect, etc; but I've heard of plenty of people who can't use tech at all or don't even dream of their phones.
This reminds me... I used to play a lot of video games. (I still play, just not as much.) Sometimes I'd have dreams where I was wearing the power armor from Metroid, or had the guns and powers from Destiny, but I couldn't use them without imagining the controller or keyboard.
Guns are the same way. It's a pisser, because I want my bananas dream action sequence, but nooooooo...
