Watching Maggie Kill Her Kids

Very strange dream from a third-person perspective, like I was watching it all in a movie. I was watching Maggie as she gave her children the poison. In the dream they were all already asleep, and she tipped a spoonful of poison into their mouths, one by one. As she did it she was talking to them, all the “good-night” things mothers say to their kids, with tears streaming down her face. I understood that I was watching this so I can better understand her current self and the reason she is so messed-up now. There was nothing I could do to stop her or to comfort her, no way to interact with the scene at all, I just had to watch the tiny sleeping mouths each accept the poison and the breathing stop, and her in a nightgown with fur or feathers around the neckline.
