I wonder if introverts are more prone to going crazy.
I am an introvert. I am always in my head, thinking about things, and myself, and myself doing things, and other people doing things, and the world, and life, and that all sounds pretty insane. If I think about it (which, since I'm an introvert, I have) we introverts and crazies have a lot in common. We both live in our little worlds secured within our minds, we think in circles and tangents, and we talk to ourselves. I mean, come on. Introversion might be a gateway personality.
Most introverts prefer standing in a corner rather than the center of a room–a safe place where we can be alone and watch people. Sometimes I catch myself doing it and i just know I look insane (not in the good way). Also, most of our time is spent in our own heads. Sure we interact with people; some of us are even good at it. But even if I am talking to you, I am also talking to myself. That is two completely separate conversations happening simultaneously, which could make anyone crazy. On a positive note, introverts are also known to be good at empathizing with others, which means we are good at placing ourselves in someone else's shoes–i.e. we are good at pretending to be other people. . . If that isn't a recipe for multiple personality disorder, then I don't know what is.
All of these behaviors make introverts sound creepy, but a) not all of us act like this (it may just be me) and b) we are pretty awesome. Introverts are usually detail-oriented, rational, understanding, reflective, and confident in themselves. But sometimes, quirks like this come out and we seem to be well on our way to the looney bin. If we are already thinking in circles, talking to ourselves, and pretending to be other people, it's probably an easy transition into a life of craziness. That's all I'm saying. So introverts, go buy a cat if you find yourself talking to yourself a little too often. I would rather you be a cat lady than a crazy lady.
