I never get paralysis when I wake up, it's only when I'm trying to get to sleep. You say it's when you try to wake up so I assume you're lucid; I've read about people being able to feel their real body lying in bed as well as their dream body when they're LDing, and as you're always paralysed when you sleep anyway, I imagine it was two conflicting sensations in a dream where you're conscious of both realities. But that's only conjecture, I don't know enough about sleep mechanisms.

Not sure if you're talking about real life precognition but I couldn't comment.
