Not code specifically, but I sometimes dream about humans in some form of "modular" sense. Like if their feelings would be contained in one class/part of a program, or their torso would be accessed via methods or something like that. As someone else mentioned, it's likely the tetris effect. I had a similar feeling while playing the game "triple" town where you want to match three bears items next to each other, I kept seeing items and people in terms of "are they next to each other" while walking around (especially when a bit of alcohol was involved).
