Never seen it. But The Happening gave me nightmares! Not as bad as Signs, but still! Course, the blood squirting 20 feet out of that guys head was totally fake, and it was a crappy enviornmentalist movie, but it was good. Ish. And its not "the Knowing" just Knowing. The Nicholas Cage movie..?
Push ( ihave both Knowing and Push at my house from Netflix and haven't watched either!)
