What are the motifs in Swamp Thing by Alan Moore?

The power of dreams is a recurring idea in the comic books. Part of the power of the comic book as it relates to horror fiction is the medium's ability to switch effortlessly between time and space, and this includes reality and the dreamscape. This not only allows the reader access to the imaginative and potentially terrifying world of dreams, it allows for an intimate window into characters. It can also provide potent symbolism and cryptic images that provide commentary, foreshadowing, or parallels to the "real" world.
