Each church have their own way of worthship the Lord?

One of my friends she is pentecostal and she played Christian music later she starts spinning around like crazy shaking herself. I got so scare what was that all about? My friend tells me that she has the holly spirit. Is this true? She also believes that woman shouldn't wear pants. What kind of church is this? I got so scare and terrified and left my friends house.
