Just something to think about: The majority of information input to your brain (mind) is visual and there is so much of it that almost all is processed unconsciously without conscious thought involved.
The unconscious mind doesn't discriminate between real and not real, it just stores the information your conscious mind will call on the next time it encounters a situation and decides how to deal with it in terms of what was the closest situation to it in the past.
All video should be approached cautiously because of this, don't put ideas in your mind that you will think of as originating within yourself when, in reality, they were -sometimes deliberately- placed there by outside sources.
Just my opinion, ignore it if you don't find it useful.
