You know the idea of shot sizes in film and TV?

We could push in even closer, to an extreme close-up—on an eyeball or nostril—but this tends to give us less information rather than more.
However, sometimes in film we can find ways to go 'inside' a character and see a representation of their interior world, for instance through dreams or hallucinations:
