False Awakening

One fateful day, a man named Doha came to visit Dohun, calling him “hyung” (meaning an older brother) as if he was family. However, there was something about this visitor that didn’t seem quite right to Dohun. He quickly figured out that this wasn’t a person at all, but rather an image from the constant nightmares that have plagued him for years.
With the arrival of Doha, other strange and eerie incidents began to turn Dohun’s previous normal life upside down. For instance, his own parents went against everything he thought they stood for, he could never seem to get any sleep at night, and the boundary between his dreams and waking life started to blend together. As a result of all the fear the young man was feeling, he became absolutely convinced that the only way to put an end to his nightmare was to destroy the creature who was now portraying the face of his brother.
Eventually, though, when he got up the nerve to confront Doha, the thing just smiled at him and said, “Hyung, you cannot rid yourself of me, that is not possible. So come, let us be together forever.” This forced Dohun to experience a chilling dilemma: was the man named Doha really there, or was he simply a manifestation of his own shattered mind?
