I could probably relate to that in an example. Back many years ago when I was in camp and doing a camp out, I had woken up in the middle of the night (no reason at all, nothing to do with a dream) and when I saw the vast night sky, I suddendly felt like I was on the bottom of the planet and would fall off if I moved (and I knew that was physically impossible). It quickly subsided and I saw a few meteors. Anyways, I live in the city and you know, the city gkow and all that. Really though, it was like a visceral or primal feeling like awe or something.
I already knew space was vast and I already liked astronomy, but seeing the night sky like that for the first time is just an overpowering feeling.
