Warning: You might have a huge, invisible spider living in your skull. This isn’t a metaphor. You will dismiss this as ridiculous fearmongering. Dismissing factors as absurd fearmongering is, actually, the first symptom of parasitic spider disease – the creature secretes a chemical into the mind to stimulate skepticism, to be able to prevent you from looking for a remedy. That’s equally well, since the “treatment” involves learning what a string saw tastes like. You can’t feel the spider, since it handles your nerve endings. You can’t view it, because it chooses what you observe. You won’t also experience it when it breeds. And it will breed. Just what exactly happens whenever your family members, friends, and neighbours obtain mind-controlling skull spiders? We are all about to discover out. Just stay calm, and understand that letting you know about the spider scenario is not exactly like having caused it. I’m just the messenger. Even if I did sort of cause it. In any event, I won’t hold it against you if you are upset. I know that’s simply the spider talking.
