I am shock after reading about your experience. I was about to write about my own paralyzing dreams when I read the subject of your post.
They are so similar, I can´t believe it.
I feel paralized, I am aware of the room, I try to wake up but I can´t. In my mind I also tend to call Jesus, while I am having the experience.
The most awful sensation is wanting to wake up but being unable to to, feeling paralyzed, stuck in the dream...and the feeling of a presence, which I believe is not good because of the awful feeling.
After I finally wake up, I feel competely drained, many times with a terrible headache.
