This is another story that isn't necessarily scary, but it makes me feel uneasy and strangely melancholic.
What kind of people were the family that lived here, that they couldn't be bothered to try to properly put this woman to rest, and instead made this ritual that seems to have just been about making sure the ghost stayed in that room by blowing the "body" around? Was the ghost mostly leaving the boys alone because she knew they had nothing to do with the family, but at the same time was bothered they were doing the ritual? Will the people who move in at some point in the future try to help her pass on properly?
We're never gonna know, and that gives this one a real "Mimi's Ghost Stories" kind of feel.
