How to get rid of this spirit?
My little sister's leg has been asleep lately it was spreading throughout her body and it was causing her pain, so we took her to children's where many specialist saw her and could not find her problem they couldn't even get her leg to reflex when they hit her knee with the medical hammer. So my mom took her to one of those spiritual people and the lady said that the reason her leg feels asleep all the time is because a wondering spirit was causing this and that it was a soul from a suicidal girl following her for 3 months now trying to take over her body, she also said that it wasn't good and that it wasn't bad for her not to be afraid. She said my sisters energy is really high and that she can overcome this she said for her to drink a tea every morning and night then to put a special rock in water in every corner of each room in the house for nine days and that the spirit will go away. I'm scared because she says she hears voices and that she hears cracking sounds. She also said that once out of no where.her entire left side felt really cold and that she realized it was twitching on its own. I'm scared I also feel as if something at night is like holding me or sometimes even on top of me hugging me.I'm her big brother and I feel so helpless. I want that crazy to leave my little sister alone we only have 5 more days remaining from those 9 days. What can I do. We make sure we all pray at night there's also a new born about two months I. the house and sometims when he's alone he always wakes up crying and his eyes sseem to wonder when. In my little sisters room. As if it following something.
