Phin's "dreamt" is about a crush that follows the speaker into sleep. The speaker dreams of someone with curly hair swept back from their face, and the sight is enough to throw the heart into chaos. The poem uses the image of a lock finally opening, as if the speaker's heart had been shut until this person arrived with the key.
The feelings are physical and almost too big to hold. The heart skips, the cheeks burn, and the speaker clutches their chest to keep it from escaping. They even wish to "unzip my skin and be set free," which suggests both thrill and discomfort.
The mood shifts sharply at the end. The opening question, "did you miss me?", comes back, but the last line answers it with a flat "probably not." The speaker admits they can't keep reaching for something out of grasp. What began as giddy infatuation closes on quiet, resigned longing.
