Trying to find out this movies name

I seen a movie couple years back and I can't seen to find it. A female scientist finds a way to teleport an object and is desperate to get a grant to further her research and as time runs out she decides to use herself in the project to get the funding but after wards she starts tripping out and thinking her boyfriend and other friend that's a girl is plotting against them. There's a door that's always locked tht she keeps trying to figure out why it's locked and she always sees like a rabbit masked person following her. I remember she runs into herself along the movie. If anyone knows what this movie is PLEASE TELL ME
