" "FantasyLand" represents innocence "
The two "emotional commanders" of happiness and worry who accidentally left their posts have to return to the brain headquarters from the labyrinthine long-term memory area, and the fastest way is to take the "thought train".
Except when Riley is asleep, the thought train cannot run, which is as convenient as the "high-speed rail" of the real world.

But it was this seemingly smooth journey that turned into an exciting adventure led by the "Fantasy Friend" popsicle.
This plot design fully demonstrates the imagination of the Pixar team. And behind every novel scene, there are also rigorous psychological concepts.
What are specific, let's briefly take stock (non-professional, only the plot prevails).
01、
The "shortcut" to the station – abstract thought.
Because 11-year-old Riley's abstract thinking ability is not yet mature, it is a dangerous construction site.
But the "no entry" sign at the door is completely useless for "illiterate" popsicles.
Once this strange place is turned on, it goes through the following four processes: non-realistic breaking - decomposition - 2D plane - color and shape, and finally trapping emotions and ideas here forever.
That day, Riley was having lunch alone at her new school in San Francisco, and for the first time came to her mind the abstract concept of "loneliness" (invisible or untouchable).
02、
Represents the childlike "Imagination Land".
There's a fries forest that satisfies your appetite, a trophy city where everyone is a winner, and a lovely White Cloud City and a house of cards.
But just as the "trio" passed through it, they found that many important buildings had been ruthlessly demolished.
Such as Soda Castle, Shiny Pony Mountain, Princess Dream Country, Muppet Animal Hall of Fame...
These "landmarks" that no longer exist mean, on the one hand, Riley's forgetting of the nonsense, simplicity, and imaginative joy of childhood during her growth, and on the other hand, it also indicates that the development of her imagination will become closer and closer to the "science" and "reality" defined by human beings.

Dream Production is where the production team has the most fun.
Bill Hader, who voiced "Fear," invited the director to spend a week backstage on Saturday Night Live, and finally had this "spoof late-night variety show + Hollywood" copycat hybrid.
Dream Studio staff would write Riley's memories into a script and then release them in real time in the dream.
The events and scenes formed in the dream are generally believed to come from people's existing cognition and memory, which contains the content of vision, hearing, smell, taste, touch, and sensation.
The bridge section that Riley reappeared in her dream that day was the scene of introducing herself in class on the first day of transfer.
With the set, lighting and makeup styling all at bay, and adding a "reality filter" to the camera, Riley felt "immersed" in her dreams, no matter how absurd the plot (teeth missing, no pants on) in her dreams.

To have dreams, there must be a subconscious.
According to Freud's theory, dreams embody emotions buried deep in the subconscious, and fragments of dreams that are recalled help us to reveal these hidden emotions.
The subconscious designer of the "Mind Task Force" movie made this gloomy space by referring to many horror movies.
Sorrow also said: "The troublesome people are all locked up here." ”
It seems that this is a dark prison!
From a conceptual point of view, the subconscious mind refers to the unnoticed part of human mental activity, including primitive instincts, impulses, childhood psychological imprints, environmental influences, concepts, personality and a series of factors.
The film clearly follows this premise, where Riley's worst fears are hidden, such as giant broccoli, Grandma's vacuum cleaner, the staircase leading to the basement, and an evil clown.
