i was reading one of the Wheel of Time books for the first time (book 4, The Shadow Rising, if you want specifics). I was at college, in the common room waiting for my next lesson, so I was reading. At that point in the story one of the characters had just gone back to his village and had started to muster a defence against some evil things, and everyone was obeying him like he was a lord or something, which is pretty weird for these people.
Anyway, someone threw something, trying to hit the bin, and it hit me instead, which snapped me out of the book, and when i looked up i growled something (i don't know what it was), and then told everyone that they should be doing as i said, because i'd come to save them from the shadow, or something like that, then i snappped fully back into reality, and at that point the buzzer went, giving me an excuse to leg it
