One time, my little brother suddenly contracted a weird skin rash on his leg. It got so bad, my mom had to take him to a doctor to have it checked on. But even after being given medication, it got so much worse that puss started coming out and it just looked like it was literally decaying. This was during the time we spent a whole year in my late grandma’s house who lived in a rural fishing village. One of our neighbors told my mom they knew a witch who might be able to help. She didn’t really believe in witchcraft but she thought she might as well try.
The witch arrived, she was a pleasant old lady who was holding a plant in her hand for some reason (she probably found some neat wild plants on the way to our house), burned some incense, took a quick look at my brother’s leg and told my mom he caught the interest of a water spirit. Apparently, water spirits can be really curious and would take fancy on people who are “strangers in their territory”. My mom remembered, my brother liked to play in this weird old spring near our house (I say weird and old because it looked kind of like a stone bath tub filled to the brim with moss, the water would come from a hole between one of the rocks and it would overflow into the ground where it drains into another hole. The water was always so cold and clean so you could use the water to bathe in or drink directly from the tub. Though I never did that because I was always afraid something would pull me from the thick moss) This isn’t an exact image but it looked kinda like this (with past me in a bowl cut to scale)
The witch said, she needed to take a stone where the culprit might be residing in, boil it in water and use the water to clean the rash. My mom was only like “Why the hell not, I’m desparate.” and went to the spring, picked up a stone and did exactly as the witch directed. Maybe my mom was exaggerating when she told it to me years later but apparently, soon afterwards before the day even ended, the blisters dried up and fell off leaving smooth, normal skin. I guess the water spirit finally lost interest in him lol. Since then we always teased him about that one time a water spirit took a fancy on him.
