The speaker in "ground" is asking for help, and the repetition makes it feel urgent. "Please" appears twice, and the request itself is said almost the same way twice: bring me back down, help me reach the ground. It sounds like someone who has run out of ways to ask and can only say it again.
The poem never says what has lifted the speaker off the earth, so the "ground" can mean different things. It might be a literal height, but it could just as easily be panic, a racing mind, a manic high, or a feeling of being cut loose from everything solid. The poem leaves that open, and the gap lets readers fill it in with their own experience.
The mood is tense and fragile. The short lines feel breathless, and there's no anger or blame, only need. What stands out is that the speaker doesn't try to fix things alone. They admit they can't land by themselves and trust someone else to help.
