I Have Had Sleep Paralysis

I've had a lot of sleep paralysis episodes, I'll start with my most recent one.
It happened last night, I fell asleep, then I woke up feeling paralysed and my chest was going up and down, like something was trying to yank the spirit, and my breath out of me. I heard alien like voices and noises. Can't remember what they said. I remember trying to make myself move but I felt stuck, and I felt something trying to get inside of me...
But it failed, then I woke up woke up... thinking it's been a long time since I had an episode like this.
