I dreamed that I was in a huge American bookstore, like a Borders or B&N, athough only the front third of it was a real bookstore; the rest of it, going as far as the eye could see, was a trompe l'oeil effect of some kind. 

It's America but it's also some kind of Chinatown or Little Tokyo — an Asian neighborhood. And I am looking specifically for a copy of a Noh play. Wherever I go, however, the "Asian Lit" section is full of Thai classics. I find a few pieces of Japanese Literature, mostly slim volumes of poetry.

I go over to another section of the store that specializes in Thai books and find dozens of very thin, uniform editions of classic Thai plays that I never knew existed before. They're shrink wrapped in plastic so I cannot open them.
