Have you watched "The Nightmare" on Netflix yet? As in, all of it? If the answer is "yes," you are a hardier mortal than I.
Maybe it's because I live alone. Maybe it's because I've only tried watching it at night, with the lights out. Maybe it's because I've experienced the utter horror of sleep paralysis on more than one occasion and fear that watching the movie all the way through will somehow trigger it again. But whatever the reason, I haven't been able to finish "The Nightmare" yet. I have tried four times.
