After getting back to the Dursley's after his fifth year at Hogwarts, Harry went straight to his room. Flopping down on the bed, Harry dozed off quickly, drifting off into a deep sleep.
As he drifted into the realm of dreams, a silent figure appeared in his doorway. Silently muttering something under her breath, the figure cast a long spell over Harry.
Suddenly, Harry's dreams changed to nightmares. Watching helplessly as Voldemort killed every single person he had ever loved, Harry screamed out.
Waking up quickly, Harry felt his scar tingling. But it was unlike anything that had ever happened before. Instead of fading, the tingling sensation increased until it was a blinding pain.
Screaming out in pain, Harry tried to get up, but the pain paralyzed him. When the Dursleys burst into his room, they did so to see Harry cringing in pain, eyes rolled back into the back of his head.
Suddenly, a blinding flash of pure green shot forth from his eyes, levitating him off of the bed.
Shockwaves of pure magical energy shot forth multiple times, flinging the random objects in the room around.
Suddenly, a change came over Harry, he suddenly grew several inches, and his black hair grew longer, going to his mid-back if he had been standing. His emerald eyes grew brighter, taking on a glow of pure magic.
Slowly floating back down, Harry lightly alighted on the bed. As the mysterious lady disappeared, a small pulse of green magic from Harry's eyes shot forth, wiping the lightening shaped scar from his forehead.
