Inception

Christopher Nolan's movie Inception starts with a simple idea... the dream within a dream.

You create the world of the dream. You bring the subject into that dream, then...
It's not strictly speaking legal. It's called inception.

Einstein established a 1 to 99 ratio between inspiration and perspiration. The inspiration in this movie is the simple idea, and the perspiration is the action from various levels of... sleep!

Fiction, action, emotions, feelings, memories... What's real, what's dream?

Isn't the brain an amazing substance?

Starring: Leonardo DiCaprio, Ellen Page, Joseph Gordon-Levitt, Marion Cotillard, Tom Hardy, Cillian Murphy, Dileep Rao, Tom Berenger, Michael Caine...

Faithless - Insomnia

According to Wikipedia, the song features Maxi Jazz singing as an insomniac while he struggles to sleep ("I toss and I turn without cease, like a curse, open my eyes and rise like yeast/At least a couple of weeks since I last slept, kept takin' sleepers, but now I keep myself pepped").

The subject is resonant with fans of dance music, since stimulant use is common in club/rave culture, and insomnia a normal side effect. The insomniac is also rather destitute ("Make my way to the refrigerator/One dry potato inside, no lie, not even bread, jam...").
