Why couldn't someone have dreamed of a beach?
When they enter the snowy dream-level, Fisher asks why couldn't someone have dreamt of a god damned beach. Valid question.
It's always bugged me why Ariadne would create such a hostile level? And I dont mean projections, I mean the physical environment of the level itself.
All the other levels seem fairly innocuous; hotel, city street, parisian neighbourhood, Saito's love-nest, Cobb's house, the office building, the wedding anniversary hotel, even limbo seems pretty benign (until it collapses). What gives.
