I watched this movie when I was little, so it was the mid – late 90s. All I remember is that it had a young girl or woman who was in a coma. And she was trapped inside her head. It would show her walking through her town but everything was empty because it was her trapped inside her head. She could hear people talk to her. Their voices were like echos and she followed them and it eventually led her out of her coma. I think there was something significant about a  movie theatre.
