《太平广记·卷三百五十一·鬼三十》
这天，王坤请来他的好友石贯，石贯刚一坐下就对王坤说，昨天夜里有个鬼三次敲我家大门，我让人去看，什么也没看见。
是日，因召石贯。既坐，贯曰：昨夕有鬼扣吾门者三，遣视之，寂无所覩。
That day, Wang Kun invited his friend Shi Guan, and as soon as Shi Guan sat down, he told Wang Kun that the night before, a ghost knocked on the front door of his house three times. I asked someone to check, but they didn't see a thing.
