This series is really the most bizarre of the 80s and that says alot.

Rem is a young looking girl who works as a private detective able to jump into dreams and nightmares in order to stop demons from draining the life force of it's victims, her default form being a short woman with a gun who could easily be mistaken for a child yet drives a car while her battle form is more akin to a warrior girl in a battle bikini or for the sake of it, aerobics leotard in her more adult forms, despite being brutally murdered in many gruesome ways, Rem always seems to escape unharmed, a testament to her abilities of being able to take charge in dreams.
Dream Hunter Rem is hard to categorise as the jarring whiplash in genres can range from thriller to fantasy to graphic horror in the space of one scene, the addition of mascots, a monk and detectives along with child characters makes this one of the 80s most bizarre anime, it really doesn't know what to do with itself.
Dub's existence is questionable, I've no knowledge of one.
Final Verdict: It doesn't know what it wants to be, nor does it know what main character Rem is supposed to be? It's too bizarre to work as anything.
