Since I moved to Los Angeles 2 years ago, it is not all that uncommon a sight to see people, mostly presumably homeless ones, having rather passionate conversations with the air next to them.
What I’m trying to figure out is, what is going on in their perception? Just the fact that they have survived this long makes me think that they are not completely unaware of their surroundings. My suspicion is they just don’t care. I can imagine a person going a very long time without any social interaction simply up and deciding (maybe subconciously) “screw it, I don’t care if anyone’s there or not” and start talking.
Or maybe they are re-living old memories. They seem to be rather familiar with the “person” they are talking to.
Or perhaps it is a sort of escapist mechanism that puts their minds away from their reality and into their imagination.
I’ve always been curious if I were to approach one of these people during the act and attempt to interrupt them if they would just ignore me or if they would snap out of it. Of course I’d be much too afraid to actually try it.
If you insist on categorizing it and saying “That’s schizophrenia” or “That’s XYZ mental disease” I’m still curious as to any possible insight as to how they perceive what they are doing: are they actually hallucinating or what?
