The speaker is haunted by someone they can't quite see. A figure appears in flashes and glimpses, standing in shade, always out of focus. Yet the speaker feels this person's warmth and love all around them, even smells their skin and hears a faraway voice calling. What's missing is the one thing that would make it real: a face, a body to hold.
The repeated questions ("is it because your not real... is it because I'm afraid to feel") show real self-doubt. The speaker wonders whether the problem lies with the distance, with overthinking, or with fear. The mood is wistful and aching, a mix of comfort and frustration, since the love never quite drives the darkness away. The ending shifts the tone. The woman in the dreams reminds the speaker that love is still real, and the last line turns the whole poem into a quiet statement of hope: despite the loneliness, "I can still feel."
