Don't worry about it, no need to be scared! Just try to take control of it.
I get it all the time, and I'm 90% sure sleep depriving yourself has alot to do with its occurance.
Yesterday morning I was lieing in bed at the end of one of those long confusing adventures when a dark silouette was stood over me telling me that it had me and there was nothing I could do about it. I was kinda scared but immediately knew I was dreaming. I always figure when weird **** is going on that I'm dreaming (which is why trippy drugs aren't good for me lol). When I tried to turn to my right or close my mouth I understood what was going on. The thing was laughing at me not being able to turn so I tried to /dontcare it and I tried to say "your not real" which I'm sure must've came out in real life has a weird exhale through my open mouth lol. When I couldn't speak properly I tried so hard to say "**** youuu" and raged haha.
Anyway I couldn't talk, and was trying to figure out what to do. I used all my concentration an tried to wake up - like face scrunched up, making myself awake as 'hard' as I could. When that failed I tried holding my breath to force me awake because I reckon your body wakes up when you don't breathe (in hindsight I don't think I actually was holding my breath in real life, especially because I stopped holding it because it wasn't working, not because I was out of breath). This always works in other dreams but not in sleep paralysis for me, so I kind of resigned waking up.
I honestly thought to myself "right, your in this dream so your going to have to just play it out" and sort of relaxed. I swear to god I decided "I might as well have some fun while I'm here" and turned the thing into a girl I know and kind of forced it to give me a handjob, but she kind of resisted and it took alot of concentration lol (having sex with girls in dreams, knowing that you are dreaming is great because you can literally do whatever you want lol). I then kindof 'made' her give me head with my thoughts, and as it was feeling good I sortof realised I was awake. Good times.
I don't think I had a hardon when I woke up, which is probably why it required so much concentration to get her to do stuff.
