Is there an etiquette to saying "good morning" when you first wake up?

This situation actually happens to me a lot where I wake up first and maybe it's some kind of camping thing or a woman I met at the hotel bar right after checking in Diamonds Are Forever style.

She keeps tossing around like my old washing machine doing the last spin cycle, and a blanket got coiled up the wrong way and it would start shaking so bad it would shut itself off and start the spin cycle over again and it's freaking me out.
