Does Scientology use subliminal messages in its videos?

I watched Scientology's "Flag World Tour-2005." I got a funny feeling from watching it. The feeling was like being in an electrical storm when the air gets full of static and ozone. I am a movie buff and am very attuned to the effects of viewing videos. I am sensitive to the kinesthetics, and synesthetics of the material. Objectively, however there is no way to measure such a thing and it could have been caused by something else perhaps. I don't really know so, I guess, that is why I am asking.
