My scary dream's

I was in my house babysitting three girls who love to do makeup.
so as they did each other 's makeup the babysitter heard a noise she said I will be right back.She went down the stair's and saw something she said who is there but no answer she heard nothing so she went to check on the children but they were not there .
So she called the parents and they said we can't find them the next day the children were all hanged in the backyard.
