If my grandmother can basically heal person or make them feel better with some words, could I?

So basically my grandmother is able to help ppl or heal them from some sickness just having a church candle, bible, and some cloth with some strange symbols. When I was once sick for long time very un usual, while I was lying on bed she was standing near and holding that ignited candle and that cloth and was reading something in Russian language. It was really scary but I got ok and got healed in next 2 days. Very fast. It was in Ukraine, also sometimes stuff happens like you get scared very much and can't pronounce word and have to repeat word like " t-t-t-this" she also reads something from book or bible which is scary as well but then you are able to talk normally again. So it is some kind of spells or what? If so is there a big chance if I learn stuff like that I could do it as well?
