I believe that the narrator of this is the same girl that the narrator of 'we intertwined' dreams of. I do not think the person she is singing of (the male narrator of the other songs on the album) literally died, but metaphorically died to the world when she left him. Perhaps now that she left him she feels guilty for in a sense killing him (he no longer really lives his life, but rather sleeps to dream of her). Although they are no longer together, she does not wish to forget the love they had, nor will he cease to remember their relationship in his dreams('we will not let time erase us.')
