This warning also applies to History majors or any occupation having to do with books, most especially dry pieces of literature which cause the brain to implode on itself, and all forms of thought to dissolve instantaneously... which, let's face it, would happen if your brain imploded... But, I digress...
An Official Warning Straight From the Rather Sleepy Mind of an Imaginative and Clumsy Student:
Regardless of what you may believe, it is actually dangerous to fall asleep with a book on your face. Never mind the potential suffocating hazards attached to falling asleep with a heavy tome blocking your airways (do not get me started), the most dangerous hazard, by far, is a paper cut. Trust me on this. Falling asleep with a book on your face can lead to paper cuts in unusual and rather unpleasant places. Like say, for example, your nose. You laugh now, but this is a serious and terrifying condition we students face on a daily basis. Do not ask me the exact specifics of how one acquires a paper cut there of all places, just know of the danger and be always vigilant my writerly friends. Always vigilant.
That is all. You may now carry on with your regular, paper cut free programming-- though, I'm not sure why you would, it's so uneventful... ;)
