I only remember one scene from this film and i watched it a couple of years ago but don’t know how old it is.

The scene i remember is:

A man looks through a window and sees his dead mother standing there, wearing the same clothes she had on when she died. All of a sudden her head starts jerking in different directions as if she is getting beaten up but with no one there. Then bug start to cover the window inbetween them. ( im not sure if the bugs come from her mouth or not). There is also a flashback scene where the man is a little boy and his mum is cleaning, a man knocks on the door and the boy lets him in. The man puts his finger on his mouth as if to say ssh. The man then goes to the mum and beats her to death.

Please help, it’s killing me .
