8. University of Seoul 

The University of Seoul is a place of higher learning, packed with over 11 thousand students… Some of whom may not actually be alive! Students of UOS have claimed to witness everything from poltergeist activity to violent spirits, unexplained sounds, and spooky students wandering around the halls.
