The world in dreams is always colorful. Everything that is difficult to achieve in daily life can become a reality in it. Although it is short-lived, like fireworks in the dark night, it disappears without a trace before you can savor it; although it may be just an outlet for emotions that are difficult to vent on a daily basis, and you may even forget its existence the next day; although we will never regard it as a reality and carefully scrutinize it, there is still a consciousness that secretly tells us that it exists and cannot be erased.
