It’s a little early for Halloween, I know, but I just read this thing (from 2012!) and it is just about the scariest, most mind-blowing shit I think I’ve ever encountered:
Jaroslav Flegr is no kook. And yet, for years, he suspected his mind had been taken over by parasites that had invaded his brain. So the prolific biologist took his science-fiction hunch into the lab. What he’s now discovering will startle you. Could tiny organisms carried by house cats be creeping into our brains, causing everything from car wrecks to schizophrenia?
Yes. Yes in fact they very well could be.
These monsters are real.
Be afraid. Be very afraid.
