Just an observation.
Each time she steps out of the elevator, she stands with her back to the wall with the elevator buttons behind her.
That's right across from the hall mirror.
She's looking at herself in the mirror.
And even at the end, when she is gesturing, most of the time she is looking partly towards the left. Towards the mirror.
Talking to and performing for the mirror.
By the way, the youtube video posted here has been clipped on the left side.
here's a link to a better quality one that hasn't been clipped.
You can see her teeth and smile when she is gesturing.

And what do you do when you're scared and the elevator doesn't work?
You walk or run back to your room and call the front desk, or you run down the stairs and talk to the front desk in the lobby.
Which is where she was last seen, but they didn't say she acted or looked frightened.
Now I don't now what to think.
