What metaphors are used in Powers of Horror: An Essay on Abjection by Julia Kristeva?

Phobias are irrational fears which have a very definite object—one is afraid of horses, says, or dogs or insects. There is a certain sense in which a fear is more manageable when it has a tangible object; the fear of the abject is truly horrifying. The phobias, then, are metaphorical representations of those primal fears which the child was forced to repress, much like art is the metaphorical representation of the abject desires one must repress.
