Who knows what "I don't want to dance in the clouds, I just want to walk on the ground" means.

Being in the clouds refers to unrealistic idealism, and dancing may fall down at any time, which indicates danger.

Down-to-earth means down-to-earth work and life.

The whole sentence means: the ideal is beautiful, but if it is divorced from reality, it is only beautiful, has no practical effect and is full of danger. I'd rather live a down-to-earth life;

Or: a certain life attracts people's attention (such as a star), which is dazzling and cool, but behind this life, people's hearts are empty, so I would rather live a plain life.

I hope it helps you. O(∩_∩)O haha ~
