My friend 35(F) got up early this morning turned on her side was awake and started to rock back and forth what was she doing hands we’re up top?

Not sure what she was doing she would rock back and forth for like a min then pause and start doing it again? Her hands NOT beneath her waist she def thought I was sleeping so she was doing something no idea what.
