First Year
You do not remember where you have been or what you have been doing. Why are your feet muddy? Why are your hands wet? Why are you awake at all and why have you not been sleeping? Only you have been sleeping. But what have you been doing in your sleep...?
Second Year
The students were woken in the middle of the night and rounded up into the great hall to sleep while the staff search the castle. You watch Harry from across the room. His tension is obvious and you know he is not asleep any more than you are.
Third Year
It's long after midnight when you and Neville return to the Gryffindor Common Room. Neville is still dancing; it makes you smile. Your first dance is a success and you drift to sleep imagining yourself in Parvati's place. If Parvati had danced with Harry more than she had. And closer. Much closer.
Fourth Year
You have been rushed out of bed and to the Headmaster's office with little more than 'Harry' 'dream' and 'father' for explanation. You are quiet while they talk, listening intently and watching more so. It is a fearful thing to have the war fall upon your very doorstep. Some might imagine you should have become accustomed to it, but they would be wrong. It is only when one's parents may die that she realises she must now grow up.
Fifth Year
Sleep doesn't come when the moment you have dreamed of for years finally occurs. Sleep doesn't come when in the midst of loss comes victory and in the midst of despair comes hope. In the midst of losing everything you begin to win; in the midst of losing everything you find....
And sleep does not come.
Sixth Year
There is no knowledge but this: it continues. You may rail at the sky but it does little good so you don't. You keep on. Because he would. Because he is.
Seventh Year
You sleep soundly. Life is good.
