This probably occurs in 70% of my failed WILD attempts. When I fall asleep because I didn't wake up enough, or for any other reason, I often have dreams about sleep paralysis. Usually these dreams are a horrible depiction of what sleep paralysis really is; I can see in them, and I can move like normal, but I still "know" it's sleep paralysis in the dream.

Four or five of these dreams have involved pain, which is a bit unsettling, but hey.
