No, there is a certain distinct style that is different from those other subcultures you have listed. One that is definitely linked with mental instability.
See timecube and "blacks for trump" as a reference.
I'm sorry to report that in my experience something like a 'schizophrenic aesthetic' does exist, at least in video.
I worked for years in the film industry, in a position where people would send videos over-the-transom to try to get financing and publicity for their projects.
Several of Ms. Aghdam's videos (i.e. https://www.dailymotion.com/video/x39ovcb) look alarmingly similar to some that I received from people who were clearly not well.
In retrospect, you can say it screams mental instability but that's called confirmation bias.
