Time Travel Begins with the Golden Eyes

Will there really be another self in the parallel world? Some people say there is, but does that mean there is another world where we can't see, and another version of ourselves lives there? Some people believe that dreams are a bridge connecting parallel worlds, which means that during sleep, the brain waves in this world overlap with your brain waves in the parallel universe in an unexplainable way. Everyone knows that when you dream, you feel immersed in the scene, as if you have experienced it yourself. Sometimes it is clear that I have never been to this place before, but it always feels very familiar. This novel and its characters are purely fictitious.
