Well, that subject line is just the beginning, i also want to know if it's possible to induce it as well, i read somewhere that you can but i want to know if any of you, who seem to research this more thoroughly than I, would happen to know how to induce sleep paralysis.

On to the story...

I had my first sleep paralysis experience last year, can't remember exactly when, but it was last year. I remember falling asleep quickly, but sort of lightly and I couldn't remember falling asleep, my dream was no more helpful in realizing i was asleep as it seemed to be through my eyes of my room. There was a sort of screeching sound that lasted but a second, and my father appeared in my rocking chair.
He had his back to me and was hunched over some love letters from my girlfriend, he seemed to be hysterical, mumbling little nothings to himself. He said some things to me, but i can't remember exactly what they were.
The open closet door, which i distinctly remember being shut before i fell asleep, seemed to cause me the most fear, it held a mystery, the deep never-ending darkness that surrounds it on a dark night.
Another short screeching sound and i remember a fear came over me, for no reason as my father was gone and the closet door was now shut, I felt weighted down and i could not move no matter how hard i tried. There was a music that made it's way into my ears, a music that inspired my fear, but, as powerful as it was, i can't remember the tune.
After a short while of this fear, my eyes wide open and rolling back into my head every time i tried to look around the music stopped and i awoke...

That's my experience... sorry to get descriptive lol
