These campus supernatural events, true and false, false and true, are like mysterious mysteries, hidden in the corners of the years. They may be traces of tragedies that have happened in the past, or they may be people's hallucinations under certain circumstances, or they may be everyone's imagination under the pressure of learning, or maybe, in those corners that we cannot see, there is really another world running parallel to us. But whether it is true or false, it makes us have a deeper respect for the land of campus. Are there any similar supernatural rumors on your campus? Is it the mysterious light in an empty classroom late at night, or the weird noise on a deserted path? No matter what, they all add a mysterious and unique color to campus life...
