Woman in Mansion Looks Upset in One Mirror and Pregnant In Another

by KY

There's a movie where a group of people go to a mansion and sleep for a night or two. The house is alive and it breathes.

There's a scene where the main character lady runs into a mirror room and looks very confused. In one of the mirrors she looks upset and another where she looks pregnant.

I don't think anyone is allowed to leave the mansion because it's trying to kill them?

Please help!
