No.3 Courtyard of Wang Jia Hutong, Pingyuan Road, Hongqi District, Xinxiang City is haunted.

From a scientific point of view: many times, people who scare themselves will have auditory hallucinations when they are nervous! It's mainly my own mentality, nothing to adjust! What you said is that it can't disappear forever! If there really are ghosts who have been reborn because of wrongful death, will so many people who have died through the ages even borrow your body and mine? So this generally does not need to be too nervous!

Supernatural: I haven't studied it much. Ghosts and gods are very ethereal things. If they exist, they exist in your own heart. Maybe your sister is weak and has recruited some unclean things. You can ask a Buddha or charm to wear it. Consider it spiritual comfort!

If it's true, move!

Good luck! Amitabha!
