The word I'm seeking is a word used to describe the feeling you get when confronted with the immensity of nature and how little we are. It's what you get when you stand on the beach, watching the ocean when a storm is coming, or looking at the stars at night in the open, it's not fear, though it has some of that, it's a lot of mixed emotions: awe, fear, contemplation, admiration, etc.
It's not a word I made up, I read it a long while ago on a grammar group and now I need it, but I can't remember it.
And it's not a common word neither, it's very specific, it's the name of that mixed feelings you get in the situations I described, neither positive nor negative, a mix of both.
Someone mentioned ¨sonder¨ on the comments, and it's quite near that, but sonder means realizing your problems are minuscule compared to the Universe, which is not the same
And I apologize for not being clear enough prior, English is not my native tongue.
