I was very religious when I was younger, & during that time I also had an episode of sleep paralysis & thought I was being attacked by a demon! I would not read about sleep paralysis for probably 15yrs, & when I did it was huge to learn what really happened to me. Even though it was only a few years after it happened I gave up religion, that experience still always made me wonder what exactly had happened to me & that is the search that finally led me to finding out about SP. Hurray for the internet! It was such a relief to finally know there was a logical explanation for it, so I no longer had to wonder if it was demons, aliens, elvis, etc.
