Ghost Leader (2020)

Rumor has it that as soon as a person encounters a ghost leading the way, people will have a blank brain and lose consciousness, but their feet will keep walking. This is what people call being led by a ghost. People who encounter ghosts lead the way will eventually be taken to some terrible places- graves, underworld and more. That happens to Song Wan Rong, which, after losing memory, for some reason, is led by the ghosts to the cemetery. What is the reason for this?
