10 Horror Movies That Will Make You Never Sleep Again
2. Mara
The concept here is simple: a big bad sleep demon does big bad things.
The film opens with a mother, Helena, who is under investigation for murdering her husband whilst both herself and her daughter insist it was the demon, Mara, who did it. Criminal psychologist Kate is assigned to look at the case, and despite her initial disbelief soon finds the legend of Mara hard to ignore.
There are four stages to Mara’s attacks: in the first, you experience sleep paralysis and see her, secondly she leaves red marks in your eyes, third she makes physical contact with you (strangling you or some other nasty gesture) and in the fourth and final stage she appears to you in the waking world; if you fall asleep in this final stage, you die.
Sleep paralysis is absolutely terrifying as it is, the last thing that needs to be added to the experience is a real demon threatening real death. So yeah, good luck sleeping after this one, you could be next.
