Welcome! I'm an atheist as well, and my non-belief did not protect from the fearsome Sleep Paralysis. And this despite the fact that I know very well what it was and what I can expect from it. Fear overwhelmed me. I experienced it twice in my life, but they did not happen during WILD. Both happened during the afternoon, and I went back into a dream in the middle of the experience.

It's scary, but not deadly, I think.
