Woahhh that's crazy @chrispy99. The feeling of being trapped in your own body sounds intense! I've never experienced sleep paralysis but during a time when I was really trying to lucid dream / astral travel I heard this huge "POP!" inside my head. It was so weird and scared the crap out of me lol. I've heard that this is sometimes a common experience but yeah, that was as far as it went for me.
