In the dream, there is MengMeng who pursues her dreams. What does it mean to wake up from a dream?

I am now standing under the sky of seventeen years old. I don't know what color is on the other side of the sky, but I know that in the future, when I look back at seventeen years old, I will still feel unforgettable, frivolous and dazzling.

Second, I can't see my future now and I'm at a loss. I found myself growing up overnight, but suddenly I felt so tired. When I heard an old song, I suddenly remembered someone. You were, okay?

Third, in the dream, there is MengMeng chasing dreams, waking up and dreaming. Flying freely is like dreaming, and it is the easiest to wake up and dream after all. Meng Xiao butterfly is in a dream, and everything outside the dream is an illusion. If it is not a dream now, how long can it last?
