They’re back. Here again for another round of “Paranormal Activity,” fans of the franchise will learn what exactly is in “The Ghost Dimension.” The fifth installation of the shaky-cam series will continue on the premise of a haunted family after a three-year hiatus.

According to Entertainment Weekly, “The Ghost Dimension” will be the final franchise chapter and will bring back reoccurring actress Katie Featherston for her fifth bow in the series. The original “Paranormal Activity” scared audiences back in 2007 and enjoyed such great success, three sequels were made in rapid succession.

The trio of films was released annually, beginning in 2010, but the “Paranormal Activity” franchise decided to take a break before releasing the fifth movie. For those wondering about the 2014 movie “Paranormal Activity: The Marked Ones,” that entry is considered a spinoff alongside “Paranormal Activity 2: Tokyo Night.” Now, the next sequel is back with a vengeance to follow yet another family facing unexplainable forces in their new home.

Below are the top three moments horror fans should keep their eyes peeled for in the new trailer for “Paranormal Activity: The Ghost Dimension."

1. Creepy Tapes
Since the “Paranormal Activity” series is all about recording things people can’t see with the naked eye, it makes sense the franchise would veer into creepy “The Ring” territory and find haunted tapes that interact with the present-day occupants.

2. Spirit Photography
A large amount of the previous story arcs dealt with grown-ups being confronted with irrefutable evidence of otherworldly presences and doubting they could be real. “The Ghost Dimension” one ups the game by giving the humans the tool to see the spirits before things get out of hand.

3. Talking Backwards? Time To Summon A Priest
One of the trailer's spookiest moments appears to be an ode to William Friedkin’s classic “The Exorcist.” Things are clearly going out of hand when the couple’s daughter is possessed by a dark spirit and chanting "Bloody Mary" backwards. But will he be any help to save her? “The Ghost Dimension” trailer doesn’t seem to suggest so.
