Woman Trapped Behind Glass by Huge Creatures

Hey there. I've been racking my brain for about a week now trying to remember the name of a horror movie.

A woman is trapped behind glass by some creatures and she's beating the glass, screaming for help but no one outside can see her (although she can see them).

In the ends, the light dimes and a huge bunch of weird creatures reach out for her.

Anyone have any ideas of the title of this movie?
