Cover art for 30 Days lyrics by Jimmie's Chicken Shack

I think this song is about a couple giving it another shot together. Perhaps even, they have put a 30 day 'trial' period to see if they can reconcile their relationship.

In the first verse, the author tries to walk himself through the possible things he might have to change to make make this relationship to work. "If I don't kid myself, if I don't care about a thing, would I be light enough to fly?" If he can prevent himself from dwelling on the couple's past (cheating? fighting? treachery?) and remove the doubts he's had, then, will that be enough to make it successful?

I think the 30 days as a 'trial' period is reinforced in the lyrics "When the race ends"....He's not sure how this trial period will turn out. Will it be safe and sound? Will they be stronger than ever, due to the trials they've had to face ("If we've lost our way, would we trade it now, for the way we found the ground?").

SECOND INTERPRETATION: The second verse could be about him getting caught 'whacking' it', as one commenter suggested. This verse could possibly be about a fight over sex that the couple had the night before, which resulted in lots of crying, and thus, staining 'streams' of tears all over the sheets. The male protagonist of the song naturally did not get laid that night. During the night, he is having an erotic dream where he receives the inspiration for this song while getting a bj from his gal in bed next to him He is woken up from this dream while jettisoning his nocturnal emissions and lays down a deluge of semen on the sheets over the previous night's tears ("laying rivers where once were streams.").

Also, "She lights the stars in the sky" could be the female's own euphemism for pulling the proverbial "Dutch Oven" on her man. As she farts and he tries to escape the sheets, the smell burns his eyes and he realizes that he is at fault for everything in the song, because an "angels can see them clear in foul weather." As his eyes burns, he realizes he must be at fault and no angel, and therefore must undertake the changes needed over the next 30 days to be honest with himself and save the relationship.
