Why do dreams and nightmares exist? Researchers have studied the meaning behind why people and animals have dreams. Yet one author offered an unimaginable and fantastical answer about what happens when everyone closes their eyes. The author of popular books such as Coraline, American Gods, and Stardust, Neil Gaiman, brought viewers into a world where Morpheus controls dreams and nightmares in the book, The Sandman.

Filmmakers developed his book into a television series that will debut on Netflix on August 5, 2022. Morpheus is the principal character on the show, but there are a few other characters that are as mysterious as Morpheus and aspire to gain his power.

Kirby Howell-Baptiste

Her character might not sport the hood and wield a scythe, but her presence makes individuals know that their time on Earth is up. Kirby Howell-Baptiste plays Death, Dreams' older sister and a member of The Endless. In some TV series such as Supernatural, Death, is seen as a cold and hardheaded figure, but Howell-Baptiste's take on Death presents a kinder side to Death.

Viewers might have previously heard Howell-Baptiste's voice as she voiced Dr. Mae Turner, the scientist studying dinosaurs' behavior, in the TV series Jurassic World: Camp Cretaceous (2021 - 2022). She also appeared in the TV series Killing Eve (2018 - 2022), where her character Elena Felton worked as Eve's assistant. Killing Eve is available on Hulu, and Jurassic World: Camp Cretaceous is available on Netflix.

Mason Alexander Park

Even though, at one point, Desire was considered Dream's favorite sibling. Desire doesn't consider the consequences of their actions regardless of how severe they turned out to be.

Before playing Desire in Sandman, Alexander Park appeared in an episode of iCarly (2007 - 2012). Their most recent role includes playing Gren in the science-fiction television series, Cowboy Bebop (2021). Gren survived the Titan War, despite being arrested for spying. iCarly and Cowboy Bebop are available on Netflix.

Patton Oswalt

Patton Oswalt voices Matthew the Raven. In Gaiman's book, Matthew once took the form of a human named Matthew John Cable. Because he suffered severe injuries from a car crash, he fell into a coma. While he died in reality, he still existed in Dreaming and agreed to take on the form of a raven.

Oswalt might not have always appeared in TV shows. In some cases, his voice served as narrator. In The Goldbergs, he was the narrator telling the story of what the 80s looked like in a multigenerational family. Aside from narrating, Oswalt played Principal Ralph Durbin in the TV series A.P. Bio (2018 - 2021). The Goldbergs is available on Hulu, and A.P. Bio is available on Pluto.
