I chatted with Wendy Greer here, and she said (after looking at her notes from one of Marie’s events), that with regard to the Three Killings, Marie says it’s not a big concern with sleeping with your head toward the Grand Duke, but if you have to sleep in that area of your home.

She didn't remember her saying anything about concerns around the Three Killings when you’re in bed. The vulnerable time is when your back is to him, which she assumed means when you’re vertical.
