I forgot how many times I woke up from my dreams in the middle of the night. I heard a strange sound coming from the next room, as if a truck was slowly starting and making a low roar. I don't know if it's my auditory hallucination or the rumbling in my head. In the hazy consciousness of half-dream and half-awake, I struggled to open my eyes, letting the boundless darkness fill my field of vision. It was like a huge sinking river, surging and surging, taking away all the light and hope. Infinitely absorb the only warm blood left in the body, which is the last place of warmth.
