Tell me about the supernatural phenomena you know or have experienced?

Although many people say that feudal superstition is not credible, I have an attitude of "believing in what is there, not believing in what is not". There are many things in the world that we can't explain scientifically, especially the things that have happened to me.

Everyone in the village says that my grandmother has psychic ability. Our family worshipped the empress, and grandma gave her a tribute every 15th. Every Halloween, many relatives in the family will go to grandma's house to worship the empress. When I was a child, my child had a headache and brain fever for no reason. Grandma always took three chopsticks, put a bowl of water, dipped in some water and patted our bodies. Then she murmured, put the chopsticks in the bowl so that they won't fall off. When the chopsticks suddenly fell, we felt very comfortable all over and didn't work hard at all. Grandma always said it was to send away the children who were pestering us.

Some relatives will come to grandma if they can't find the disease in the hospital. Grandma went to the house over there to worship God, and when she came back, she lay on the kang and began to chant Buddhist scriptures. Grandpa told us that grandma invited the empress and told us to keep quiet. Grandma would start saying some strange things and grandpa would write them down. These things are also very strange, such as sand that walks a certain number of steps in a certain direction, such as hundreds of meters collected in a certain direction, such as red scissors. After these seemingly irrelevant things are handled according to grandma's method, the patient will get better gradually. Grandma will be particularly tired every time she invites the empress like this, and she can't remember what she said. It's amazing.

I don't know if this is supernatural, but my grandmother can't give us a reasonable explanation for these things, except that she was taught by a teacher when she was a child, and she doesn't remember what that teacher did.
