Merv (as he is better known throughout the series) is Dream's jaded, street-wise, cigarette-smoking janitor. While his appearance can vary based on who is viewing him (for example, William Shakespeare saw a turnip-headed version of Merv in Sandman #75 (March 1996)), Merv is generally portrayed as having a pumpkin for a head. His appearance is based on Jack Pumpkinhead, a character in L. Frank Baum's Oz books.
Matthew was originally Matthew Cable, a long-time supporting character in the Swamp Thing series, but because he died while asleep in the Dreaming, he was offered the chance to become a dream raven and serve Dream if he wished, and he accepted.
