True story told to me from a coworker.
My coworker grew up in a what he called a haunted house, he told me that at night with all the lights off, the shutters and blinds closed, there would be a light shining in one of the rooms in the shape of a cross, and no matter how hard they tried to find the source there was no natural explanation for it’s existence.
One night the aunt woke up to see the disembodied head of a man glaring angrily at her, she became afraid and closed her eyes beginning to pray, when she opened her eyes she saw the head again this time the man smiling before disappearing.
The family was a devout Pentecostal family, and practiced a charismatic spirituality speaking in tongues and discerning spirits.
I told my coworker that his story sounds like a spirit in Purgatory and explained the doctrine of Purgatory.
Remember to get your November prayers in for the deceased and all the Holy Souls, especially during Advent leading up to Christmas when most souls are released from Purgatory.
