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 definitely written code in my sleep. As to whether it would work in real life who knows, but I’ve had dreams that I was coding. It’s very annoying to do it in your sleep and then go do it in your awake as well.
