Scientologists ACTUALLY believe the evil alien ruler Xenu killed a lot of aliens (Thetans) from around the universe by bringing them to earth & blowing them up inside volcanoes. They believe the souls of these aliens (these souls are "Body Thetans") have attached themselves to us & cause many of our mental & physical ills. Members who know about Xenu will attempt to deny it or pretend like it doesn’t matter. They are required to sign a contract binding them to silence on the matter. Lower level members don’t know about Xenu & accordingly deny everything because they honestly don’t know.
To rid ourselves of "Body Thetans" & also “engrams” (past negative experiences stored in our unconscious mind) so that we can become “clear”, we have to go through "auditing" with a member of the “church” who uses an "e-meter" to measure our “reactive mind”...... & we have to pay lots & lots of money for “auditing” (purchased in 12.5-hour blocks, costing anywhere from $750 for introductory sessions to between $8,000 & $9,000 for advanced sessions) & to take courses on Scientology to advance to higher “levels” in the “church”. The “church” has also taken a very hostile stance towards psychiatry & psychiatric drugs irrespective of the fact that some people require medication to remain adequately functional in everyday life. They deny the reality of chemical imbalance & profound mental disturbance & accordingly do NOTHING to effectively stabilize the dangerously unstable. The “church” has been known to withhold prescription pharmaceuticals from member (with deadly results).
Scientology is undeniably a cult. For more information on what a cult is & what their damaging effects are, please visit the link provided at the bottom of the sources. Just know that Scientology DOES qualify by meeting these 5 criteria:
(1) It uses psychological coercion to recruit, indoctrinate & retain its members. (2) It forms an elitist totalitarian society. (3) Its founder leader is self-appointed, dogmatic, messianic, not accountable & has charisma. (4) It believes 'the end justifies the means' in order to solicit funds & recruit people. (5) Its wealth does not benefit its members or society.

This video is a bit longer. It’s a CBS “48 Hours” special on the mentally disturbed son of Scientologist parents who refused to put him on the anti-psychotic drugs that would have stabilized him & prevented him from killing his mother:
