Good biopic, not so much a documentary
We enjoyed this, as both my wife and I have experience sleep paralysis a couple of times in our lives. My wife found it especially eerie when the subjects mentioned the shadowy figures with red eyes, as during her one experience with sleep paralysis she had awaken to see a shadowy dog with red eyes in her room.
The visuals and descriptions of the states of sleep paralysis are very accurate.. I never experienced the "shadow men" myself but remember vividly as a child waking up in my room, hearing noises I couldn't describe, being unable to move or speak - I tried to cry out to my parents in the next room, but all I could do was breathe and wheeze. Next thing I knew I woke up in the morning, and I knew what had happened to me was real, but couldn't describe it to anyone.
It's amazing how so many of these experiences include similar imagery and phenomenon.
However we were both sort of disappointed that there was no scientific aspect to this "documentary" at all whatsoever. We kept wondering when the personal stories would end and we might get to hear from someone specializing in the science of sleep - anybody that might be able to provide some insight into what might be happening in the human brain during these episodes. Nope, nothing.
That's the only thing that takes away from an otherwise great film, and I feel that without that aspect it's sort of hard to call this a "documentary" on sleep paralysis..
