I'm Methodist..I don't understand sanctification

Im Methodist..my mom is sanctified..I don't understand the Holy Spirit..it scares me..she preaches over me and prays over me like I'm here guinea pig, instead of getting behind the pulpit..I can't live my life comfortably because every move I make she says I'm going to hell or being disobedient and I'm 42 years old. When she prays it feels like someone is putting voodoo on me..it's very uncomfortable. I feel like she's harassing me..how can I make her stop throwing her religion on me without my permission
