The question about hypnosis lingers in my mind: Can hypnosis really change a person's memory? The answer is yes. So can the altered memory be restored? Yes, as long as a special signal is received, the person's memory will be restored.

I dragged Sara downstairs and my phone suddenly vibrated. The caller ID showed Nana, so I hung up. Then Sara's phone rang too. She looked at the caller ID nervously, but still pressed the answer button: "Hello, Nana..."

I was startled and quickly grabbed the phone and hung up. We had already run to the second floor and heard hurried footsteps above our heads. I grabbed Sara and ran downstairs. I looked up and saw Nana's face hanging between the stairs, staring at me.
