It's happened a couple times fairly recently and was just weird...once it was in the morning I got up at like 6 and was still tired so I decided to sleep in longer. Then when I woke up I couldn't move at all, I opened my eyes but everything was rather blurry and I could hear things going on in the house, people talking and what not though not all of it was real.

Kept trying to move and felt too much pressure holding me back...but eventually kept fighting it till I could move which took a crap load of mental energy not sure if it actually helped or not. It was more annoying than anything because I was thirsty. I didn't really think of it as a PTSD thing though...I thought most people had sleep paralysis at least a couple times in their life.
