When a person has no idea of the role he plays in the construction of the world he inhabits, and he has no awareness of the deep changeability of  significance of the world, he is a naive realist.

If a person suddenly experiences a shift in the significance of the world, without recognizing the permanent possibility of yet more shifts, he will interpret this event as a lifting of the veil of illusion and the revelation of the true world, and he will become a naive realist for a second time.

Some people never get bored with lifting and shredding veils. Realism does not have a monopoly on naivety.
