That makes a lot of sense to me given my personal experiences. Reading this thread is interesting. I've never heard the idea that you can't read in dreams. The last couple of months I've been having dreams where I'm doomscrolling headlines on an app, and I'm actively reading the headlines to myself. But since I'm doomscrolling , I notice them and move on. I'm aware of when I'm dreaming, so sometimes I'll laugh to myself and my partner about the stuff my sleep- psyche comes up with. I don't know if this is a recent development, but I can't remember ever trying to read something in a dream and being frustrated that I can't.

I have a number of problems that result in unusual and unhealthy sleep patterns, so that probably contributes to odd dream experiences.
