Nightmare Solver

[Non-horror themes, watch it boldly] [The protagonist and villain have high IQ + fast pace + logic genius + high energy throughout] The life of Li Mingliang, the top student in high school, was cut in half on a rainy night. One second he was still red-faced arguing with his mortal enemy over the logarithmic formula. The next second, the hollow snake-shaped pocket watch handed over by the man in black set his time hand into a strange loop. The antique mirror newly bought by his parents can eat people, and the reflection in the mirror is always smiling; there is a mezzanine hidden in "The Interpretation of Dreams by Duke Zhou", and the strange girl in the yellowed photo wears the same gold medal as him; what is even more frightening is that every time he tries to uncover the truth, the world will restart with the sound of rain - and this time, he finally saw the sawdust on his parents' sleeves in the cracks in the mirror, and his face that disappeared on the podium... "Do you believe what you see with your eyes?" When the seventh cycle started, Li Mingliang clenched his pocket watch and discovered that the girl in the photo on the cover of the watch was standing on the podium wearing his school uniform. Whose memory is being modified in this experiment in the name of dreams?
