Sorry to hear of the family turmoil in your life, red. I have heard some stories about the belief in witchcraft in the Philippines called kulam, especially centered on the island of Siquijor. Kulam traces it's origins back to Haiti, and is supposedly used to to inflict pain and suffering to a person who has wronged someone in a certain way. The person who was violated supposedly goes to a person who practices kulam (witchdoctor or mangkukulam), and brings an item or a strand of hair that belongs to the person who wronged him or her, and the witchdoctor uses that to cast a spell. The person who has the spell cast upon them supposedly get sick with fever and constant vomiting, or in worst instances, they may die. This sickness supposedly cannot be cured my modern medical means. The only way to counter the spell is to seek the help of another mangkukulam or through other witchdoctors known as an herbularyo or albularyo.
There’s a far more potent and evil form of kulam called barang. Barang uses insects like cockroaches, spiders, or flies to inflict pain to a person. What the barang does is put these insects inside of a person’s body through evil spells. The victims of barang do not only get sick through high fever and vomiting. The insects mentioned above allegedly come out of their ears, nose, and anus or through wounds that began as swellings until it explodes and the insects come out. Sounds like some scene out of a horror movie. Superstitions are prevalent in the Philippine culture just as they are in many other cultures around the world.
I recall a superstition of my ex-wife who is from Central America. It is really harmless and quite silly in my opinion, but she believed it. The superstition is that if you pack a suitcase or bag of your possessions on New Year's eve, and you take it outside, and run around the house carrying it, then you will make some trip during the coming year. Beats having bugs crawl out of your ears!
