This is another poem that I have enjoyed reading. Your words are never unconnected to your title.
As I am a fan of the rhymes in poetry, I very much enjoyed that. I also like the variation; 1st stanza is A,A,B,B, the 2nd A,B,A,B. You then begin again with A,A,B,B, and I can't tell if you meant to finish with A,B,A,B, or not, but you finish with A,A,A,A. Which is still a nice change.
I can't really say that I found flow to the poem though. It begins that way, and most of your lines are generally the same syllable count, but your variations in that are slightly scattered. I've noticed that it's generally line 3 that is extended.
In your first stanza, Line 3 is longer, to assist in maintaining a closer flow, perhaps adding one or two more words to Line 4 could help? For example, "as you lay in your bed"
Although it's only one word, and also used before the last word in Line 3 as well, I feel that it adds that extra bit to help, but doesn't add too much, so that it takes away from your image.
In your third stanza, Line 2 also feels to me like it breaks your flow in that section. When reading, I want to read; THE sun is shining. Your 1st line in this stanza is simple and short, but gets longer in the second line.
If I may suggest for Line 2;
Sun shines as the moon blocks the shadows.
I think this is tricky, because like Moon, you say "the" and I am wanting to do the same with Sun, but it's difficult to bring the syllable count closer when I want to add a word to the longer line lol.
However, all of that aside. I know that when writing, those aren't the particulars that most people are thinking about. I find for me, it's the content, and I very much enjoyed yours!
