Anyone else have trouble sleeping after seeing it?

Ok, so its not scary what so ever....but i rented it(would never buy it, although it IS humorous and would be a great addition to my bad horror collection) and started watching it kind of late after a long day at work. so, after a few beers and slipping in and out of sleep, i finally turned it off. however, this was only after the massive amounts of flashing on the screen. going from B&W to color and random flashes of images and what not. all i know is that night i could barely sleep. i think the odd filming style screwed with my head. anyone else have this happen?
