Talk about bad timing. With Halloween only three months away, the latest Paranormal Activity trailer was set to be released any day now — then it hit the net right when virtually every movie site was buried in Comic-Con coverage.

The trailer for Paranormal Activity 3 opens up with old home video camera footage of two girls playing in a backyard in 1988. We then start to get flashes of creepier scenes capped with the two girls setting up a camera in front of mirror and chanting, “Bloody Mary,” in the dark.
 
Take a look at the trailer below and let us know what you think. Paranormal Activity 3 hits theaters October 21, 2011.
