Just reality check every time that you wake up.

If you see something scary happening, and you react to it, well, you'll be dreaming, so what harm could come to your partner?
Once you wake up for real, and she's doing something scary, she probably deserves it hahaha

I think you are confused about the definition of a False Awakening, as opposed to the sort of REM hallucinations that can persist after sleep. What exactly is it that you're talking about, here?
