Liu Yi watched the other person and answered, "I said, I just woke up not long ago, I don't know anything."
"Awake?" Dr. Zhang asked, puzzled.
Liu Yi fell silent for a second, as if in thought.
"Yeah, I feel like I was just dreaming..." Then he looked at the other person again and continued, "You probably were, too..."
"Ah?" Dr. Zhang made a pained expression, recalling his recent actions in the empty hospital corridor, "Nonsense, how can a dream be that realistic?"
Upon hearing this, the other person immediately showed that "can't explain to you normal people" expression commonly seen on patients with mental illness, ranting...
"How is it nonsense? How do you know dreams can't be realistic! Perhaps you're dreaming right now! I might just be a person in your dream!"
