Some people say that dreams are the entrance to a parallel world.
In dreams, you can glimpse yourself in another time and space, walking through a completely different life. People with a clear enough will can even control every word, action and choice in their dreams, and the only rule in the world will never change. When the first ray of light falls on the face in the morning, it is the key to returning from the dream to reality.
It's just that no one knows that besides this rule, there are fateful exceptions.
Intention: Cherish the warmth in front of you, refuse to repeat the same mistakes, and seize the opportunity to start over.
