Interesting skeptoid article on sleep paralysis and some of its supernatural interpretations that have occurred over the centuries. Having been a sufferer of sleep paralysis since my early 20's I can understand how many have interpreted them as supernatural events, even though I don't subscribe to the supernatural interpretations myself. Nonetheless, it is a very bizarre and terrifying experience when they do happen. In recent years I have rarely been getting sleep paralysis episodes. I notice that the article states that Prozac seems to inhibit them from occurring. Since Prozac is an anti-depressant and since I am on an anti-depressant (Celexa) for my anxiety disorder I wonder if that is why I no longer seem to be getting episodes of sleep paralysis.
The mind is a strange and complex computing device and although science has made great strides forward in understanding its inner workings there is still apparently a lot more to learn.
