I had no idea Sleep Paralysis was a thing! I used to get it all the time as a teenager. It sucked, nice to know it wasn't a worry. My episodes weren't super nightmarish thankfully. A few times they were a vivid dream mixed with wakefulness, where I could see my dream and my room at the same time. It was freaky. More often it was just not being able to move even though I was awake. It felt like paralysis and was so scary as I tried to get myself to move and wake up.
