The obvious ones in British classical balladry are "The Cruel Mother" and "The Maid and the Palmer" (Child 20 & 21) and "Thomas Rhymer" (Child 37) (this probably isn't news). I'm afraid I can't think of broadside examples however. You might also be interested in the Norwegian ballad "Draumkvaede" (The Dream Song) which recounts a journey to heaven and hell. A significant amount of literature on this ballad is available in English. See esp. Michael Barne's "Draumkvaede." Best of luck.
