Spying a Horror Film

Date: 1/25/2017

I wasn't even in this dream, it was like I was an invisible third wheel that could see everything and just followed people. Anyway, I saw this family, a mother and a father with a son and a daughter. They apparently had a past daughter who died and was now back for revenge and was really gross and dark and black wet hair and an ugly black dress. I remember her trying to kill the mom who was trying to protect her kids.
