Who?

I lifted my hand and my reflection stood still. I'm so tired, I think I'm seeing things. I began to walk away but, I stopped because I saw movement in the mirror. My reflection was opening its mouth and closing it, as if it wanted to speak. I looked at the mirror closely to see if I could read what it was saying. The silent speaking stopped, and the reflection stood still. It's eyes widened. It didn't blink once.
