When last seen in this space, Emily Carroll was sketching some mighty nice zombie fanart. Now she has a new project up: four-panel snippets of her recent dreams. You know how boring it is to listen to someone else go on and on about their weird dream? This is not that. Carroll shows brief vignettes and presents everything visually, which, when you think about it, makes a lot of sense: Since dreams are largely visual, drawing them is more economical than writing about them. Like most of us, Carroll has some disturbing images in her dreams, but her drawings of them seem almost like surrealistic gag cartoons — most of them end with some sort of a punch line or non sequitur.
