Oh that is very sad indeed. That is a common feature in some bad marriages. It also is seen in Voodoo as well as Mediterranean “evil eye”.
American’s Santa Claus has a bit of that too “He sees you when you’re sleeping / he knows when you’re awake” – as does some of the American Christian “kitsch” art where Jesus’s eyes seem to follow you around the room, or in homes where the parents place a big picture of Jesus where the child has to see Jesus before sleep to show that “Jesus is watching”.
All ways of getting in someone’s head.
