http://thesaurus.reference.com/browse/ghost

A ghost is a very good "embodiment" of evil (even though it has no body) and that is why I thought I should briefly touch on it. The poem clearly has a dark aspect to it, but evil in an actual form is something that the writer was good at both hinting at and showing. A ghost is both evil and dead, so it is perfect. The poem is very direct in saying that this is not a happy place, you need to leave, and that is why the ghost is one of the better examples of that.
