A dream leaves the speaker with a strange mix of certainty and blankness. They can't recall the person's name or voice, the very details we usually use to hold onto someone. They don't even know whether the two of them have met in real life, or ever will. Yet one thing stays sharp: in the dream, they fell in love for the first time.
The speaker seems both puzzled and quietly moved. The casual phrase "Funny thing is" keeps the tone light, almost shrugging, but the final line drops that lightness and speaks plainly and sincerely. What lingers is the feeling, not the person. The short, simple lines and the pause before "Or voice" make the poem feel like a half-remembered thought, spoken softly just after waking. The mood is tender, wistful, and a little hopeful. The poem suggests the speaker is open to love, even if it so far exists only in a dream.
