Dreaming of You imagines a time after someone has gone, and the speaker is alone in a bedroom, left with the traces of that person. The opening line, "When the world reclaims you," suggests death or some other kind of taking away, though the poem never says which. What it does say is that the speaker will keep what remains: bloodstains become roses, and fallen threads of skin become white, shimmering feathers.
The speaker's feeling is a mix of grief and devotion. Nothing is thrown away or cleaned up. Instead, pain and the body's leftovers are transformed into something tender and almost holy. The ending is the most striking part. A warm breeze carries the feathers one by one into the speaker's lungs, which feels both intimate and a little suffocating. The mood is dreamlike, quiet and aching, with beauty and unease held together. The scattered, stepping layout of the lines also mirrors the slow drifting of those feathers.
