Little girls play with their dolls as if they were real babies.
They feed them, dress them, comb their hair and sing them songs.
They boil imaginary tea in plastic toy kettles and drink it. They even offer you some. You play the game and you drink it. It makes them happy.

Little boys, play cowboys and goes against imagined enemies. Sometimes they dress up as Super Man or Peter Pan or whatever.
They built sand castles, houses in trees, etc.

Children are happy and have a lot of invisible friends to play with. They are never alone. They create their own reality.

Grown adult artists, with imagination skills, have written a lot of fairy tell stories, that you read to your kids before bedtime. Kids adore these stories, they always want more, they never have enough.

And then, they go to school and it kills all of their imagination. They enter the brainwashed society, where everything is so rigid, so limited, that it leaves them powerless for the rest of their lives. They become androids.
