sky/ceiling

When I came out of work today to go to the training course, the sky was grey and foggy and looked like it was only about 10 feet up. It looked like you could raise your arm up and touch it. I remember thinking thoughts in those same words when I was at Kenyon. I also remember thinking thoughts with the words, "It's like living on the inside of a white dome." I remember thinking thoughts with those words, but I didn't remember the experience, because when I experienced it again this afternoon it seemed new.
