ending?

Rating: 9/10 (2 January 2007)

At the end....when she wakes up in the cave with her own self but younger, did she get out or did she dream of escaping only? I am confused. I thought she got out by running to the jeep and whatnot, and who was the girl next to her inside the car? Any insight on this ending would be greatly appreciated. I thought it was an awesome movie, and I also heard it was based on true events. Anyone know if this is true as well? And what was with the birthday candles? Was that really her younger self? What does all the stuff at the end mean? If there are any other movie buffs out there who want to chat about stuff , add me to msn bbygrl_76@hotmail.com :)
