Yumekui Merry

Briefly about Yumekui Merry manga:

Yumeji has the power to forecast a person's dream based on the multicolored auras that surround them when he looks through his fingers. His skills are unpolished, but when he sees a black aura, he knows for certain what that person will see that night: a nightmare. Yumeji has been having nightmares himself recently, where he is chased endlessly by an army of cats until he ends up in a vast marsh. To escape this dream, Yumeji tries to awake from it...but then finds out that even when he sleeps, his nightmares will never leave him alone.
