I've noticed recently that sometimes my dreams are two-dimensional, and look like mobile app UIs or webpage DOMs. Just this morning when I woke up I realised, "that was Stacker News!"

I was struggling with media upload and linking. This is interesting, because not only had I not used SN much in the few days leading up to this appearance, but also, I haven't uploaded media even once.

When I was much younger and began programming, I had a few dreams where I was "thinking in code", although I don't recall visually seeing the terminal or IDE. Has anyone else noticed similar effects?
