Picture this scenario: You're napping on a breezy Sunday afternoon in the hammock of your backyard, enjoying the peace and quiet of your suburban utopia. Slowly, your left hand eases up, wraps around your neck and you awake to find your own hand locked in a kung-fu grip on your throat. You pry it loose with your other hand, finger by finger, until it relents and you're left there staring at a hand that suddenly doesn't feel like your own. While it sounds like something from a B-grade horror movie, it's actually a very odd and very real medical condition known as "alien hand syndrome" (AHS).
