Just as Inside Out's principal players are all symbols, so are its locations within Riley's head. From Preschool World to Dream Production Studios, from the Train of Thought to Hockey Island, everything is a visual representation of an abstract concept.

Some of these symbols are spot-on. The shelves of Long-Term Memory when viewed from above look like a brain, for example. The Train of Thought is an actual train. Other symbols take less literal forms. The Memory Dump symbolizes depression, for instance. It's deep, dark, and hard to get out of on your own.

These symbols of Riley's consciousness may be specific to Riley, but they're also easily recognizable to most viewers.

"I don't like it here," Sadness says of Riley's Subconscious. "It's where they keep Riley's darkest fears." Lo and behold, they have terrifying run-ins with broccoli, the basement, a rampaging vacuum, and one seriously scary clown named Jangles. If there's nothing on that list that creeps you out even a little bit, nothing that you can relate to, then thanks for reading, Chuck Norris. We loved your work in Dodgeball.

Speaking of lists, here's a rundown of all the metaphoric locales in Riley's mind—you know, in case you want to go on a symbolic sightseeing tour:

• Headquarters: This is where it all goes down. Joy, Sadness, Anger, Disgust, and Fear man a control panel in HQ, and monitor all of Riley's mental activity, including her emotions and the formation of memories. Riley's eyes are their window to the outside world; HQ also has large windows in the back that allow Joy and her crew to see the rest of Riley's mind, too. Headquarters. Get it?

• Personality Islands: These represent aspects of Riley's personality, linked to her Core Memories. When she's 11, they include Family Island, Friendship Island, Honest Island, Hockey Island, and Goofball Island. When she's 12, they also include Fashion Island, Boy Band Island, and Tragic Vampire Romance Island.

• Long-Term Memory: Riley's long-term memories are stored in these massive, library-like corridors on the other side of the Memory Dump. They're regularly pruned by Mind Workers; knowledge that they don't think she'll ever need again, like most of her piano lessons, for example, get moved from Long-Term Memory to the Memory Dump.

• Memory Dump: The final resting place for memories that are permanently forgotten, like—sob—Bing Bong.

• Imagination Land: This large, colorful zone looks like a theme park, and it's home to everything Riley dreams up, including Cloud Town and Trophy Town, lava pits, a French fry forest, an imaginary boyfriend assembly line, and Preschool World, an entire subsection dedicated to the stuff Riley dug when she little.

• Train of Thought: Representing Riley's stream of consciousness, this literal train meanders around her mind.

• Dream Production Studios: This bustling studio manned by Mind Workers cranks out Riley's dreams like they're blockbuster films. They treat what happened during her day as a script and use a reality distortion figure on their cameras that transmit live to Riley's sleeping noggin.

• Abstract Thought: Riley's abstract thought resembles a large, empty warehouse. Anything that enters it when it's turned on goes through four stages of abstraction: non-objective fragmentation, deconstruction, becoming two-dimensional, and becoming non-figurative. When Joy, Sadness, and Bing Bong enter, for example, they're eventually reduced to just colored shapes.

• Subconscious: This dark and thoroughly creepy corner of Riley's mind contains her deepest fears, like broccoli and Jangles the Clown. It looks, and sounds, like a cross between a jungle and a dungeon.
