Sandman (folklore) in the context of "Dream (character)"

Dream of the Endless is a fictional character, an anthropomorphic personification who first appeared in the first issue of The Sandman, written by Neil Gaiman and published by DC Comics. One of the seven Endless, who are inconceivably powerful beings older and greater than gods, Dream is both lord and personification of all dreams and stories, and all that is not in reality (which, in turn, Dream may define by his existence). He has taken many names, including Morpheus, Oneiros, Kai'ckul, and the Sandman, and his appearance can change depending on the person who is seeing him. Dream was named the sixth-greatest comic book character by Empire. He was also named fifteenth in IGN's 100 Top Comic Book Heroes list.

After the events of The Sandman: The Kindly Ones that led to Dream's death at the hands of the Furies, Daniel Hall becomes the new Dream.
