I am Hmong, and my religion is still very traditional. My grandpa was one of the gifted ones that god send to help people on earth. Hmong relatives from all over the world will come and dwell in our house just for him to see this possessed woman. This woman is very ill and sick when anyone is around her, but when no one is around, she will eventually turn into a demon and start chewing on sofas and clothes and will start stripping off her clothes, and speak in a demonize language. But when someone enters the room, she will fall back down, and will eventually faint like nothing had happened.
According to my culture, Hmong people believed that this comes from hereditary. Some Hmongs refer this to as, "tsev neeg tsis huv..." This means that some peoples' hereditary are not clean; their family was once possessed by demons, and when they die, they will come back and possess their own children, or grandchildren. This woman, was believed to be possessed by her own mother, who died ten years ago from exorcist.
Her husband and her came to our house, asked my grandpa to help her get rid of the devil. She screamed and yelled and chew on everything that is on her way. It took a while for her to recover, but definitely faster than most religion. She screamed and screamed and desperately calling out for her mother, and for devils to take her back.
After she recovered, she did not recall this, of what had happened to her. She does not remember a bit about what she is about to turn into, but she only remembered being unconscious.
One question I don't get it is that why would demons be interested in us human for? And does religion also matter?
