Jinwoo's nightmate might have two sides. One, he associated gunwo to the killing of his father after the murder incident and tthe doctor's story of how gunwo murdered his family. It's how the mind interprets fear, the mind is so strong it could create a whole new memory that doesnt even exist and make you believe its really what happened. Its a trauma response. The second, the nightmare could also be the reality which was triggered after the murder incident. It could be that gunwo really is involved in his father's death but jinwoo forgot about it since it was so painful and he himself was almost half dead (based on early chaps) and therefore he's hallucinating in that state and couldnt understand that it was gunwo who killed his father. Again, his memory loss is a trauma response and the trigger of memories recently is a result of what he has seen and heard guwon do to others.
