Main character specializes in going into people's minds to get rid of night terrors and negative feelings during sleep. However, one night while in a patients mind, he manages to get stuck inside. For days. The main premise of the story is how the main character lives off of a land of a mad world, constantly hunted down for being a foreign entity.
More will be added once I finalize certain things... like giving the main character a name.
This would probably be a short animated series, roughly 6-12 episodes long.
