In Upstairs, Carrie informs her boyfriend she isn’t pregnant – won’t he be thrilled! — then walks into a party with a host of personalities -- all interrogating her about her new baby. Is she losing her mind? No, she’s inside her mind. And her whole mind is probing her worst fears about herself: Is she too pathetic or – dangerous, even – to ever be a mother?
When Carrie tries to escape the wild, darker aspects of her own psyche, she hides in an unknown room and finds an unknown woman. Who just happens to be wearing her same outfit. But cooler. In fact, she has Carrie’s same face. But cooler. In fact, she is Carrie — inner Carrie. They are both … Surprisingly … Okay. And Carrie gets Carrie pregnant. By jumping inside of her own vagina.
