So, after asking around, we don't remember who put in the semicolon. Here's an explanation of the title by the concept creator though!
"My original title had been "If in your dreams the flood," in homage to "If on a winter's night a traveler," this novel by an Italian guy named Italo Calvino. With the imagery of a flood having been taken as inspiration from "Ophelia," the Lumineers song. It beats me what the semicolon is supposed to represent actually." ~Electro
