Please Kill Me Before I Wake Up

When sleep is no longer a rest, but a life-threatening prison. Chen Mo frequently fell into strange dreams nested in layers. Abandoned subway stations, endless corridors, countless twisted "selves" peeping in the dark. A phone call from me tore open the false shell of reality. A cruel command kept ringing in the dream: Please kill me before you wake up. Can't tell which is illusion and which is reality. Is he going to kill the phantom in his dream and survive, or is he living in a big dream that will never end?
