If your looking for more on this, the podcast Oh No Ross and Carrie have a 4 or 5 part podcast on Scientology. They report on fringe science, claims of paranormal activity, and spirituality by taking part. They went through the process of joining the church. It went on for a lot longer than it should have as they never hide or lie about who thy are or what they do.
The way they get busted is hilarious and perfect. I strongly suggest you listen to it if it seems interesting to you and not look at the spoiler.
