I always like to dream, not the "dreaming" that I like to dream about, but the real dreaming while sleeping. Sometimes dreams are endless and groundless, and you forget them as soon as you wake up; sometimes dreams are about happy things, and you feel good when you wake up; sometimes dreams are so real that people can't get back to their senses for a long time, and can't get rid of the emotions in the dream for a long time, so suddenly the idea of recording dreams comes up.
