What does this phrase mean?

It’s a poetic way of calling someone a daydreamer I would reckon.

Wondering is wonderful.

He wonders about things in a delightful way.

Curiosity is a constructive virtue.

His curiosity is the main reason to achieve his dreams.

I find the phrase problematic. Curiosity implies uncertainty. There is something that you want to find out about. A dream is an imagining of what it is like for something to happen Between the curiosity and the final end is the discovery process, which is of interest precisely because you can’t imagine where it will lead.
