Unlike a lot of horror movie franchises, which just substitute a new group of characters to get terrorized whenever it's time to make a sequel, the Paranormal Activity films focus very tightly on a single family, with the first two films linking up to each other and establishing a large mythology that's the plot of the new third movie, Paranormal Activity 3, which opens this Friday, October 21. So if you see the new one this weekend and find yourself curious about what happened before, we've got the giveaway for you.

Two lucky winners will receive DVD copies of both Paranormal Activity and Paranormal Activity 2-- though we don't recommend watching them together, since there are some nightmares you can't recover from. To enter, just click on over to our Facebook page, "Like" it if you haven't already, and then leave a comment on this contest post. Tell us about your favorite memory of being scared in a movie theater, and we'll pick two favorites as the winners. The contest ends at 12 am EST on Monday, October 24th. If you enter, please make sure we can contact you via Facebook. If you have it set to where we can't message you, your prize will go to somebody else.

The winner will be notified via Facebook direct message and asked to provide their mailing addresses (no P.O. boxes please). Prize packs will be mailed directly to the winner. No purchase necessary. Failure to comply with the rules will result in disqualification and subsequent mockery. Good luck!
