I'm a big wimp when it comes to horror movies, so I've never seen Nightmare on Elm Street and probably will. But after reading an interview with the director last night, I still decided to diagnose everyone involved with a rare genetic heart condition caused by a defect in a cellular sodium pump. And according to Google, it may even be true.
According to an online movie magazine, the director of Nightmare was inspired by a true story, which he describes as follows:It was a series of articles in the LA TIMES, three small articles about men from South East Asia, who were from immigrant families and who had died in the middle of nightmares—and the paper never correlated them, never said, ‘Hey, we’ve had another story like this.’ The third one was the son of a physician. He was about twenty-one; I’ve subsequently found out this is a phenomenon in Laos, Cambodia. Everybody in his family said almost exactly these lines: ‘You must sleep.’ He said, ‘No, you don’t understand; I’ve had nightmares before—this is different.’ He was given sleeping pills and told to take them and supposedly did, but he stayed up. I forget what the total days he stayed up was, but it was a phenomenal amount—something like six, seven days. Finally, he was watching television with the family, fell asleep on the couch, and everybody said, ‘Thank god.’ They literally carried him upstairs to bed; he was completely exhausted. Everybody went to bed, thinking it was all over. In the middle of the night, they heard screams and crashing. They ran into the room, and by the time they got to him he was dead. They had an autopsy performed, and there was no heart attack; he just had died for unexplained reasons. They found in his closet a Mr. Coffee maker, full of hot coffee that he had used to keep awake, and they also found all his sleeping pills that they thought he had taken; he had spit them back out and hidden them. It struck me as such an incredibly dramatic story that I was intrigued by it for a year, at least, before I finally thought I should write something about this kind of situation. This history, especially the South East Asian origin of the men, sounds a lot like a condition called Sudden Unexpected Death Syndrome.
First of all, is that the best name for a disease ever, or what? You know right where you stand with that one. I picture the typical consultation for an SUDS patient going something like "Mr. Jones, I'm afraid your test results show you have Sudden Unexpected Death Syndrome" "Oh, and what are the symptoms of that diiiiiEEEEAAUUGH!!!" *thud*.
This would totally work in a movie. The dashing assassin is trying to kill an evil dictator, but can't get past his security. He hears the dictator is going for a doctor's visit, so he sneaks into the hospital, steals a pair of scrubs, and impersonates the doctor. Then he says "Generalissimo, I'm afraid your test results show you have Sudden Unexpected Death Syndrome" "Oh, and what are the symptoms of that diiiiiEEEEAAUUGH!!!" *thud* as the assassin cuts off his head with a katana and then sneaks away into the night.
...but getting back to the point at hand, this is a real condition, most common in Laos (a country which needs no introduction to long-time readers of this blog), and probably caused by a defect in a sodium channel in the heart that causes it to occasionally go into electrical spasm during sleep. Sometimes the heart manages to get back into a normal rhythm on its own; other times it can't and the patient, as they say, wakes up dead. Other features of the disease include palpitations, prolonged QT interval on the ECG, and being attacked by demons.
Wait, what?
Yes, people who survive an episode of heart spasm from the disease very often report being attacked by a demon. Generally, they'll wake up paralyzed, see the demon sitting on top of their body, casting some sort of evil spell on them, and then suddenly the demon will disappear and they'll be able to breath and move again.
This disease is pretty hereditary, so if lots of members of your family report being attacked by a demon in their sleep and then dying inexplicably in their sleep shortly thereafter, and then all of a sudden you start being attacked by a demon in your sleep, you can be forgiven for feeling a little terrified.
So what's up with this demon, anyway? Well, he sounds closely related to another, much better understood demon - the one that haunts people with sleep paralysis. Sleep paralysis is a pretty common disorder caused by poor synchronization between the wake up switch for your conscious mind and the one for your motor system. If your conscious mind wakes up before your motor system does, you experience it as being awake but paralyzed. You also feel a crushing weight on your chest, which is the easiest way for the sensory system to interpret your inability to breathe. A few seconds to a few minutes later, the motor system finally wakes up and the paralysis stops.
Some, though not all, of the people with this disease also report seeing demons during the period of paralysis, usually but not always sitting on the victim's chest. The half-asleep brain loses a lot of its sensitivity to reality and kind of exists in a world of its own. That's why most people have had the experience of, for example, a dream about a fire alarm going off at school, and then waking up to find their alarm clock ringing (and the basis behind the old joke about the man who dreamt he was eating a delicious marshmallow and then woke up to find his pillow missing). The brain doesn't have enough processing power online to actually decode the alarm clock noise, so it just makes something up - like the fire alarm dream.
The half-asleep brain definitely doesn't have enough processing power online to come up with hypotheses for why you seem to be awake but terrified and paralyzed with a crushing weight on your chest. So it makes something up - usually a demon sitting on the chest. That explains everything - the terror, the crushing weight, the paralysis, why you woke up so suddenly. This is just a theory, but it's the one that makes sense.
Sudden Unexplained Death Syndrome seems related to this in some way. Either the heart spasm from SUDS causes some of the same symptoms as sleep paralysis, or the stress and unusual motor state of sleep paralysis activate the SUDS patient's latent tendency to go into heart spasm. I'd guess the former, since the article reported the victim screaming, which AFAIK people in classic sleep paralysis can't do. In either case, the two of them seem to coincide pretty closely.
So now we have enough information to figure out what happened to that poor immigrant boy in the news. He had a few episodes of heart spasm in his sleep, which presented to him as waking up and seeing a demon trying to kill him. Each time, he felt like he was dying - understandable since his muscles weren't working and his heart had gone crazy - and each time, he found it harder and harder to recover. Being an immigrant outside a culture where this sort of thing was almost normal, he figured either that he was going crazy or at the very least that he couldn't tell anyone what was going on, and so he just refused to sleep. When his family finally convinced him to sleep, all the stress and coffee and sleeplessness was enough to start the heart spasms again, and he died. And we ended up with a movie about a demon who kills people in their dreams.
Apparently I am not insane, because no less an authority than Wikipedia has also proposed a Nightmare-SUDS connection.
By the way, the sleep paralysis thing? It's made its way into various different world mythologies. In Laos, the particular demon that afflicts SUDS sufferers is called a dab tsog. The Northern European version, who being limited to garden variety sleep paralysis can scare people but not kill them outright, is called a mare, and is the origin of the word "nightmare" (the big black horses came later, are are purely a folk etymology) |
