Mother and her two kids (a boy and a girl) are tormented by ghosts that turn out to be time travelers. I think the dad has recently died and the boy has some behavior issues and he is getting kicked out of or about to be kicked out of school. The mom has a boyfriend. There is a guy trying to get the mom to sell their house. Later, the kids get sick when they try to leave the house.
Remembered some more info. Mom’s boyfriend is the kid’s science teacher/mentor. This is a more recent movie (newer than 2010…probably 2015 or 2016)
I watched it on Netflix or Hulu or Amazon Prime.
The Diabolical (2015)
