THIS IS IT!
I HAVE TO WEAR A CPAP HEADGEAR WHEN I BED AT NIGHT.  MY LONG WAVY HAIR WAS ALWAYS GETTING KNOTTED UP IN IT, AND PULLING MY HAIR.  REMEMBERED THE OLD DAYS WHEN MY MOTHER WORE A SLEEP CAP, TO KEEP EVERY HAIR OF HERS IN PLACE.  TRIED THESE.  THEY ARE GREAT!  KEEPS MY HAIR IN ONE PLACE, AND THE HEADGEAR DOESN'T SHIFT AROUND ON ME WHEN I SLEEP. P.S.....MY HUSBAND THINK I LOOK CUTE IN THEM.  LOL.
