Dream Reading Leaves Traces

My name is Liu Hen, an ordinary young man who is unemployed after taking the postgraduate entrance examination. My daily routine is very simple: sleep until noon, eat noodles made by my mother, and be woken up by my sister kicking the door. But my night was anything but simple. Every night when I fall asleep, I enter a dreamland - lions, deep sea, doomsday wasteland. The system said that I am an "observer" and can only see but not change. I watched those people die in front of me, over and over again. Until one day, I saw my sister in my dream.
