A mother (mid to late 40s+) with her son and daughter (both mid to late 20s) have issues in there home with a paranormal entity. The son finds his sister in the bath/shower being raped by a paranormal entity. They have other issues but that’s the only one a can majorly remember. The daughter has black hair and an alternative look, the son had dirty blonde hair and a beard, and the look was a dirty blonde but more on the blonde side I believe. The description on the moms hair is iffy, but the son and daughter are as valid as I can remember. At least I hope haha.
There’s a movie called Paranomal Entity that has multiple scenes depicting an adult brother finding his adult sister being assaulted by a paranormal entity, in the house they share with their mother. He finds her traumatized and topless in the bathtub, and then later finds her being raped in her bedroom by an invisible force.
