These paranormal occurrences are often associated with the building's long history, though the specific details of any alleged haunting or the identity of the supposed spirits are not deeply elaborated upon in the available descriptions. Unexplained sounds of walking have been heard by visitors. Areas within the museum are sometimes noted for sudden drops in temperature. The ghost of a librarian is said to appear within the museum.
