A strange existential feeling and celestial bodies

peace.
A. We live on a blue globe, floating around a ball of fire, and surrounded by a moon that rules the oceans. Stars, galaxies, and endless black spaces. Looking becomes natural to me, and the more I look at things, I can’t get rid of the feeling that existence is quite strange. I am amazed as if I don’t belong to all of this, and in a moment I have to wake up from a dream that, to my surprise, is reality. Does this happen to you from time to time, too, and do you find yourself identifying with the feelings?
B. Do you have any advice regarding fear (which causes not-so-healthy functioning) of celestial bodies like the size of the Sun and how close it is to us? And if you say it’s some kind of psychological problem, I’m not so sure about that, just because I find it logical. I’m also not comfortable that the Creator entrusted us to such a star. I have a deep puzzlement about it.

thanks.
