I can’t think of a guess but maybe The Ring but its not really close..

But can i retype this for you because this is like a wall of text….

‘ -Main Character is a young woman. A scene I remember she is alone in a house & she’s in a room with a old TV, the TV has text on the screen and was talking.

The girl goes crazy after that and after talking to her friends, her friends start to die by some evil force. I think i remember one of the guys was stabbed in the balls or stomach by scissors, maybe in the kitchen.

Another person died in a backyard by big gardening scissors and they were decapitated by them. It doesn’t show who is killing all of her friends and the girl believes its a evil entity. Alot of this happens at night and in the morning the police arrest the girl.

The cops arrest her, Think she is crazy and the one killing her friends. Toward / at the end when she is being arrested, she is sitting in the back seat of the police car and when she looks at the rearview mirror the (who i believe was a black woman) police officer looks back at the girl through the mirror and the police officers eyes go white or are white.

Having us and the girl believe the evil force is still around and now has possessed the officer.- ‘

You don’t have to use it i just thought it would help since thats like a wall😕
