Life is like a dream

Before getting up, I had a dream. I dreamed about my freshman summer vacation. I was sorting out some things in the dormitory to prepare for the sophomore year. The instructor sizheng seemed to come and check the dormitory. After greeting her, she asked her what the size is now. I hesitated, my mind swept through all kinds of work from the university to the present, and then quickly converged on one point. I felt that they were all Nanke's dream, so I replied weakly that they were freshman. Suddenly woke up, sleep unexpectedly could not tell whether it is in the dream or just in the dream, just not to sigh life as a dream.

If we can repeat our lives, what will be the difference?

BTW did not notice whether the dream was black or white. Recently, it was found that the dream was colored. Sometimes you can clearly remember the picturesque green outside the window.
