In Scientology, body thetans are immortal spirits of aliens killed by Xenu which put themselves inside the bodies of humans and cause them bad emotions and mental illness. Scientologists believe that people who finish training in the last levels of Scientology can use telepathy to help other people get rid of their body thetans and become happy.
