The World According to Snape

"Snape often had nightmares of the night Voldermort had fallen. Lying there in the Shrieking Shack, covered in blood, feeling the last beats of his heart slow. When out of nowhere Harry had appeared. Like an angel from the darkness. He bent down and slowed the blood oozing from his neck. Stroking his black hair, whispering that it was all going to be okay." Harry/Snape Slash.
