This song is about the trepidation towards the afterlife; it's not death you fear since there's no avoiding it, but rather the notion of the difference, and exactly how different the afterlife will be/is, and you are afraid to accept it even though you are already in your spiritual form. However once you realize that your attempts to try to rekindle a past life are futile after your departure from it, it is much easier to accept what has happened to you, and forget about your fetid Earthly carcass.
