People who experienced sleep paralysis, what did you see, felt or heard?

I used to have sleep paralysis on a monthly basis.

Most of incidents were basically the same. I’d be sleeping on my back. I could see the room, but couldn’t move my eyes. Usually dark figures would appear in the peripheral of my vision. The figures would terrify me. I had to scream myself awake. Usually started as a low growl and developed into a scream. My significant other could testify to this.

But a few occasions stand out. Once, I had a dark figure whisper into my ear. It was some sort of nursey rhyme. The craziest part of it, is that it was mono. I could only hear it in the ear that was being whispered into.

The scariest was I was surrounded by dark figures and they were stabbing me in the abdomen. The pain was so intense. I went to the hospital that morning because my appendix had burst.
