I have found this example, using the human counter:
In this movie, the two female ghosts who appear before the main character, a man who works as a potter, are both victims of a war-torn society. この映画で、主人公の陶工の男の前に姿を現す二人の女の幽霊は、共に戦乱の世の犠牲者。
However, I also see this as one definition for 位 :
い ( i ) 【位】
counter for ghosts
*Interestingly enough, I found the Japanese term for the Trinity is 三位一体 (さんみいったい)
If this counter is in fact used as a counter for ghosts, would someone be kind enough to demonstrate its usage?
