This typically happens to me when I’m in the middle of something or when I’ve been trying to think my way through some problem for a long time.
It’s not zen because it’s like I literally don’t exist, and when I do come back around, I think “shit I’m wasting time I need to get back to things” and then it happens repeatedly so i dont make any progress.
Fun fact, my grandfather worked on the Saturn V and, according to my father, got in an argument with Von Braun at least once
I mean not fun because of working with Nazis, but fun because it’s interesting history
