I think it had “yoru” in the name maybe. It was about this teen? 16 or around there. He got this power where when he slept he could go into other peoples dreams and influence their memories and what they do. He used this power to get revenge on the 3? people that killed his sister or something. I remember there was a part where the police baited him out by tricking him into slapping someone awake and the mark was on them in reality.
