When he was a little boy, after Lin Chen's prank disturbed him, Lin Yan started to have hallucinations, or whatever you would call them. Though he knew it wasn't real, it was hard for him to understand and come to terms with what he was seeing. He would always believe that what he was seeing was entirely accurate. As a little boy, it was challenging to comprehend whether it was reality or a hallucination. He couldn't distinguish between his imagination and his demons. After the night where he fainted in the graveyard, Lin Yan was brought back by Lin Jing. Since no one could comprehend how terrified he was, they left him alone in the room.
