The person dreamed about is a man, but the song is no more specific, so the song can have many different nuances:
If it's about a lost lover, the emotional resonance is negative, in the sense that he's moved on, and she hasn't.
If it's about an estranged father, then the impact of dreaming about him could bring father and daughter back together, which has a more positive resonance.
Most poignantly, it's about a dead person, maybe a dead grandfather, in which case there's a poetic beauty to the song, where the living grand-daughter brings him back to life in her dreams, sustaining the memory of him long after he's gone. This is the affecting meaning that means the most to me.
