i like this one because the herb seems to spring from the words.
But yes dark mode messes it up a bit .

In image 2 and 3 the words seem to far from the picture to me , feels disconnected in some way .

Image 4 :
Sharp and clean looking with that edge , you could change that back to blurry to point out the dreaming a bit . But a logo that people will remember must have a sharp edge or border .
My suggestion would be to put the word dreaming on like a smile , like it follows a imaginary 3D ball . With the D and the G of dreaming near the stars and the A down below the herb . It would make it all more dimensional and give more focus on the herb .

Just my humble view on it , for it's already a nice logo for what it stands for , at least i could not find any hidden meanings in it as i do with many other existing logo's and signs .
I hope my input was a bit helpful :-)
