Also check out The Fables comicbook series. The writing is interesting & quick. The subject matter very adult oriented but without the horror element. It might be helpful too you.

Have fun with it.
In college I had a very progressive film professor & I did a paper on the dream world as the gateway to horror. Films like Phantasm, The Shining, An American Werewolf In London, Susperia, The Fog, & alot of others have an elemental dreamlike quality to them where the audience can't seem to decide if its a dream or reality. Alot of the fairytales also have this quality. Some silent films have this in spades. The Silent Beauty & the Beast is a great example. Its sets & such were unreal.
