And the underlying animal is still there too. It's fully in control at birth, and gets drowned out as we mature (for some people, less than others).
Small children are little more than animals, which is why they're so unreasonable.
It's my belief that the reason the written word or things like clocks are usually unreadable in dreams, is because the animal is both illiterate and innumerate. Dreams are the animals understanding of our waking experience. It knows these patterns are important and how they relate to other things, but it has no fucking idea what any of it actually means.
