In case the first five Paranormal Activity [1] movies didn't spook you, another one is hitting theaters on Oct. 23. The new one, titled Paranormal Activity: The Ghost Dimension, is (supposedly) the final film in the franchise. The trailer is filled with creepy kids breaking mirrors, saying cryptic things, and chanting "Bloody Mary" backward. They're typical horror movie shenanigans, but by the time a dark, shadowy figure rolls up behind an unsuspecting guy, you might find shivers are going up your spine. Check out the trailer!
