Sleep paralysis is a medical condition that many people experience, even though very little is known about it. The paralysis happens when the individuals are in between being asleep and fully awake and many do not feel like they are dreaming. Sleep paralysis is a heavy influence on horror films, including A Nightmare on Elm Street and Insidious. The cause of sleep paralysis is unknown and while some may believe it is merely something in the individual’s head, others believe that they are experiencing something supernatural or demonic.
Described as a horror documentary, Rodney Ascher tackles the subject of sleep paralysis through a series of well-produced, and often terrifying, re-enactments. A common thread in many sleep paralysis stories are the “shadow men,” who appear in the room. The film allows the stories to play out as, the subjects retell them, and the audience is allowed to make their own conclusions about what is happening. Are these shadowy figures merely hallucinations or is there something else going on?
Probably something that's real interesting about sleep paralysis is how it can be used to explain many supernatural events the people apparently experience, ranging from hauntings to alien abductions. Of course, some of those who have experienced sleep paralysis believe that its not a natural occurrence, with many individuals even turning to Christianity after their sleep paralysis experiences, since they were convinced that it was something demonic that was tormenting them.
If there is any real criticism that can be given to The Nightmare, it is the fact that the film opts not to provide any real scientific reasoning for sleep paralysis, other than the fact that examples of this condition have existed all throughout history. The film is probably more akin to shows from the 1980s and 1990s, such as Unsolved Mysteries and Sightings, which would use stories and re-enactments specifically to scare the viewer. Without a doubt, The Nightmare is quite successful in that regard, with the re-enactments often being quite intense, with there even being the odd jump scare.
The subject of sleep paralysis is undoubably an interesting one and its depiction in The Nightmare will probably result in you having trouble sleeping afterwards.
