The trailer for new film Mara effectively captures the horrors of sleep paralysis.
It’s described as “being conscious but unable to move” that occurs when a person passes between stages of wakefulness and sleep.
It’s produced by the same team behind Paranormal Activity and Insidious, both successful franchises in their own right.
Starring Olga Kurylenko, the film follows a criminal psychologist who, upon investigating the murder of a man, begins to fall victim to an ancient demon which murders people in their sleep.
