Dream of the Endless is a fictional 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. 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.

The Sandman is the pseudonym of several fictional characters appearing in comic books published by DC Comics. They have appeared in stories of various genres, including the pulp detective character Wesley Dodds, superheroes such as Garrett Sanford and Hector Hall, and mythic fantasy characters more commonly called by the name Dream. Named after the folklore character that is said to bring pleasant dreams to children, each has had some thematic connection to dreaming, and efforts have been made to tie them into a common continuity within the DC Universe.
