I watched this movie a long time ago, when I was a kid (it was far from a kid’s movie) around 2007, so details may be partially incorrect. The movie was likely created around this time. I don’t recall the exact premise, the woman seemed to be a former human test subject on the run.
I recall a scene where the main character is having a nightmare. In the dream, the woman is curled up inside a blue bubble-shaped container filled with water or other clear liquid. She is unconscious, eyes closed with an oxygen mask on her face. Black tubes/wires surround the bubble. A scientist in a white lab coat is walking around the bubble, examining her.
