As a "sleep paralysis" sufferer myself all these allegations of shadow men, demons screaming in your ears or demons calling your cellphone are bullshit!!! I cant emphasize that enough. The only thing that was indeed true is that you feel like you're suffocating. And FYI, YOUR GOD DAMNED EYES AREN'T OPEN WITH "SLEEP PARALYSIS"!!!!!! THAT'S WHY ITS CALLED "SLEEP PARALYSIS", BECAUSE YOU'RE CONSCIOUS BUT CANT SEEM TO WAKE UP; AND BY WAKE UP I MEAN: MOVE A MUSCLE OR OPEN YOUR FREAKING EYES!!!! Hence the name "sleep paralysis". All these testimonies are so fake! I can assure you "sleep paralysis" has nothing to do with the supernatural! NOTHING WHAT SO EVER!!! If it was so "TRUE" why not record them in the act???? Oh, that's right ... BECAUSE THEY'RE LYING!!!!!!!!

I had a sleep paralysis only once in my life. The period when I had it I was “haunted” by poltergeist-like phenomena (which I experienced while fully awake over a period of several years), Due to my own experience I don’t think the science explanation with hallucinations makes sense. This is something else but why it happens and why particular people experience it I don’t know.

I didn't know much about the topic going in, and I don't feel like I know much more after. I would have preferred a combination of testimony with some scientific research. Aside from that, the testimony wasn't all that interesting. This can be skipped.

Just like Mr. Ascher's previous documentary "Room 237" (which I consider to be overrated drivel), this is once again a series of interviews with people of various degrees of sanity. Most of these are not very interesting and the reenactments they're set to are often quite cringey.
