Fending Off Dementors

Can you feel the cold fear of the dementors as they suck all the happiness out of you? 

In Harry's third year at hogwarts, the train is mistakenly taken by dementors. Lucky for Harry, Lupin saves him from the dementors with his great patronus. I love the great suspense in both the book and the movie when the dementors attack. 

Better get your chocolate handy.
