"Wake up!" I heard this sentence again and again in my dreams, and I spent a little time every day analyzing the meaning of this sentence. I have several interpretations: Maybe it's telling me to wake up from my dream, stop sleeping, I'm going to be late for work, wake up quickly! Maybe it has a deeper and more philosophical meaning, don't live in confusion anymore, are you willing to be ordinary? Wake up! Maybe it was because I fell asleep in class one day when I was a student. My roommate who was in class with me tapped me on the shoulder and said, "The teacher is here, wake up!" It's okay, but when I was old, doctors or family members were crying beside me, "Wake up!" I don't quite understand what this sentence means. Maybe I will never understand its true meaning for the rest of my life.
