The symbolism surrounding Lady Gaga is so blatant that one might wonder if it’s all a sick joke. Illuminati symbolism is becoming so clear that analyses like this one becomes a simple exercise of pointing out the obvious. Her whole persona (whether its an act or not) is a tribute to mind control, where being vacuous, incoherent and absent minded becomes a fashionable thing.
Gaga is a term that immediately refers to absent mindedness. Here are some synonyms taken from a thesaurus:
Given to lighthearted silliness: empty-headed, featherbrained, flighty, frivolous, frothy, giddy, harebrained, lighthearted, scatterbrained, silly. Slang birdbrained, dizzy.
Afflicted with or exhibiting irrationality and mental unsoundness: brainsick, crazy, daft, demented, disordered, distraught, dotty, insane, lunatic, mad, maniac, maniacal, mentally ill, moonstruck, off, touched, unbalanced, unsound, wrong.
“Gaga” is probably the easiest word to say in the English language, as it is often the first sound emitted by babies trying to imitate speech. So her name basically says: I’m a lady and I’m empty-headed. This empty head can filled with any crap you want. Imitate me young people. This state of mind is achieved after successful mind control.
