Paranormal Activity [movie trailer]

The film has been getting rave reviews on horror blogs and is touted as the next Blair Witch Project; think shaky-cam scares at home:

After a young, middle class couple moves into what seems like a typical suburban starter tract house, they become increasingly disturbed by a presence that may or may not be somehow demonic but is certainly most active in the middle of the night. Especially when they sleep. Or try to.
