Dreamland (2007)

Meghan and Dylan are crossing the Nevada desert in an old car to visit her foster parents, and Meghan sees a little girl alone in the desert. They stop at the "Little A'Le'Inn" diner, a weird place decorated with alien motif, to eat a hamburger with milkshake and they have a conversation with the bartender Blake, who tells stories about UFOs. They leave the diner and they have to stop in the middle of nowhere due a car problem. Dylan faints and Meghan sees the little girl and ghost that tell her that they know who she is. Is Meghan losing her mind or are the weird events for real?
