The Eighth Day of Disappearance [Suspense]

I've been feeling a little weird lately. My shadow is cut. Every seven nights, the shadows disappear, only to return the next morning when you wake up. It's so strange, even if my life doesn't change, I still want to see where my shadow has gone. I followed the first shadow, which took me to a drowning scene. I saw the running shadow and the girl struggling in the water. But my hands can only pass through the other person's body. The girl died and I returned to reality in the morning. Seven days later, I continued to follow the second shadow, which took me to a hotel where I heard running and screaming. I wanted to hold the person who fell, but my hand went through the other person's body again. … It turns out that my shadow has been watching the deaths of others. What should I do, how should I bring back my shadow. Are all the murderers caught? -- Purpose: Confront evil and defeat the past
