Afterthoughts

Sleep Paralysis:
You wake up, but you can’t move a muscle. Lying in bed, you’re totally conscious, and you realize that strange things are happening. There’s a crushing weight on your chest that’s humanoid. And it’s evil. "The witch riding your back"

You’ve awakened into the dream world.
