Westworld: Watch The Nightmarish New Trailer

Dreams apparently "mean everything" in Westworld, but a new (and slightly NSFW) trailer for the upcoming HBO series feels far more like a nightmare.

The clip is focused on Dolores (Evan Rachel Wood) who, according to the official synopsis (via ScreenCrush), is a "provincial, beautiful, and kind rancher's daughter, who begins to discover that her entire idyllic existence is an elaborately constructed lie." And that all definitely comes into play here.

Based on Michael Crichton's 1973 sci-fi thriller, the series is about a virtual reality theme park set in the Wild West that goes off the rails when something goes very wrong with the android inhabitants.

HBO also recently launched a viral site called "Discover Westworld," where you can learn more about the "first vacation destination where you can live without limits."

Westworld premieres Oct. 2 on HBO, and it's one of several new fall TV shows we can't wait to see.
