There's schizophrenia and there's the online notion of a schizo. The latter is pretty much just a paranoid sperg.
I have some peculiar tendencies which may put me in the "schizo" department. For example, I could be recommended a video by YouTube's algorithm where it says that it was uploaded "X years ago," and, upon judging the number to be ominous, I would refrain from watching it, even against my own desire. I'm not naturally superstitious, but this is one strange OCD[?] habit that I developed, I believe, from years of isolation. The more secluded you are, the more you mentally stray from the mean, from what is considered normal. But I have yet to hear whispering voices or see spectres.
