You in Parallel Time and Space

Do you believe there is parallel time and space in this world? I believe it. There was a pair of twin brothers in my class in junior high school. My younger brother and I were at the same table for three years. After graduating from junior high school, I went to another city to attend high school. Communications were not developed at that time, so we lost contact. More than ten years later, I went back to the city where I was in junior high school to attend a class reunion. At the dinner table, I mentioned the twins from back then. Everyone looked at me like I was a monster. It turned out that in their memories, the twin brothers did not exist at all. This made me re-examine the real world. As layers of mysteries were uncovered, I suddenly realized that human technology seems to be very powerful, but in this world full of unknowns, our scientific discoveries are not even the tip of the iceberg. The discoveries and inventions of existing technologies are not enough to explain most daily things. We are accustomed to calling things that cannot be explained as metaphysics, or even superstition, thus missing many opportunities for research and discovery.
