This Book Is Full of Spiders: Seriously, Dude, Don't Touch It (John Dies at the End #2)
You will dismiss this as ridiculous fearmongering. Dismissing things as ridiculous fearmongering is, in fact, the first symptom of parasitic spider infection-the creature secretes a chemical into the brain to stimulate skepticism, in order to prevent you from seeking a cure. That's just as well, since the "cure" involves learning what a chain saw tastes like.
You can't feel the spider, because it controls your nerve endings. You can't see it, because it decides what you see. You won't even feel it when it breeds. And it will breed. So what happens when your family, friends, and neighbors get mind-controlling skull spiders? We're all about to find out.
Just stay calm, and remember that telling you about the spider situation is not the same as having caused it. I'm just the messenger. Even if I did sort of cause it.
Either way, I won't hold it against you if you're upset. I know that's just the spider talking.
