Have you ever had such a delusion? I woke up suddenly at three in the morning. I always felt that there was another person lying on the pillow, and my fingertips felt bitingly cold.
When you struggled to turn on the light, there were black nail marks on the sheets that didn't belong to you, and the self in the mirror was staring at you with a weird smile that you had never seen before.
What's even more frightening is that friends and colleagues around you begin to whisper: "Didn't he die in that old building a long time ago?" Now, it's your turn to face this hunt for "existence". Are you sure that the person alive now is the real you?
