The double meaning you speak of in the English language, is what I refer to in a more general sense as 'meta'. This phenomena has actually expanded further socially into double meaning phrases within the English language. You need to be fairly precise with your choice of words/phrase when reprogramming the subconscious mind, if there is double meaning, then it's really up for grabs on which way your subconscious will interpret it. It is likely that the dominant interpretation absorbed from a ''meta" phrase will be based on it's ease or ability of being visualized, as well as the emotion attached to the individual interpretation of the phrase.
You are exactly right about there being something nefarious in the creation/modification of the English language. The modulation of alpha waves influences speech comprehension when listening to audio. The low alpha waves produced by TV effects creativity & induces detachment, making you unfocused & open to suggestion.
It is apparent to me that in many TV shows, there is significant use of 'meta', or more accurately in regards to this discussion, it is referred to as a double entendre. This is defined as a word or phrase with a double meaning, but with the second meaning primarily having a risque or indelicate context. The risque factor causes for a greater emotional response to the phrase, which the subconscious can more readily absorb, along with any scripted phrases closely timed in sequence afterword, yet still separated by context. This is done intentionally for comedic value which most commonly can be seen in short 'laugh track' comedies, where a phrase is first introduced as a normal, but then followed by a comment that gives it sexual context. This is a different concept from the discreet methods used in which I refer to as 'meta' brainwashing. Our social adaptation to the double entendre status in the English language has led to a wide array of phrases that can be comically responded to with the annoyingly overused phrase "That's what she said." So it is clearly apparent in our social constructs that we as a society have become more sexually focused in our thinking.
I will elaborate on the methods further in a post to my feed. That was a great video you made outlining various lies being taught in our society, I'm excited to see what you post next. Following...
