When I was a child, my mother used to say demons are the result of our own sins

Not the most sensitive thing to say, but in her own way, she was trying to say, if you know you're a good person, you have nothing to fear.

I don't think you sound ER'ish at all to me.

As mentioned above, many MANY neurotypicals believe in demons and nobody chases them to hospital.

I personally believe I've had demonic experiences, and yes these were outside of episodes, although one very disturbing one was in the midst of an episode.

FTR, my cousin swears he witnessed a possessed person (I won't go into it) and I have no reason to disbelieve him.

Me, personally I think that there's so much more to this reality than what we can see, taste and smell on a daily basis. And its not all in our head all of the time.

Besides, all rumours have to start somewhere.
