In the world of Pixar’s Inside Out, our long-term memories are mazes and our dreams are made in a Hollywood-esque production studio. The new trailer for the film, about the personified emotions inside a young girl’s head, shows how Joy (Amy Poehler) and Sadness (Phyllis Smith) encounter these brain lands as they go on adventure to make things right for Riley after a fight that impacts the girl’s core memories.

So now we have a better sense of how a movie that takes place internally actually works. That, and there are some San Francisco jokes. “There are no bears in San Francisco,” Disgust, played by Mindy Kaling, says. “I saw a really hairy guy. He looked like a bear,” Anger (the perfectly cast Lewis Black) responds.

And we learn the impact of brain freeze.
