The speaker of "Wish" seems to catch themselves in the middle of a feeling. "Suddenly I found me in here" suggests they didn't plan to end up thinking this way; the longing simply arrived, and they noticed they were already inside it. What they want is simple: for someone else to be thinking of them. Then, almost at once, the wish shrinks. If that's too much, they'd settle for "at the very least" being looked at.
That small step down is the heart of the poem. It makes the speaker sound shy, a little unsure they deserve the bigger thing, and perhaps protecting themselves from disappointment by asking for less. The word "in here" could mean a room, a crowd, or the speaker's own head, and the poem doesn't say, which leaves the feeling open for the reader to fill in.
The mood is tender and vulnerable, with a hint of loneliness. The short lines and plain words keep it quiet, like a thought whispered rather than announced.
