Pain.
It was burning his skull where his scar was, he saw a black hooded figured in front of him, wand pointed at Ginnys head, laughing, "You thought you were rid of me, Harry? I've only but begun." said Voldemort, twirling his wand through his pale slender fingers.
"No!" he yelled, trying to move but seemed bound in place, Ginny looked as if she was in a world of pain, he couldnt stand her like this, he had to help, struggling more he said, "You're dead! We killed you!" Voldemort only laughed more.
"If you killed me how am I here?" Voldemort smirked, "Avada Kedavra!" Voldemort yelled, Ginnys scream was muffled, and then she fell limply and ceased breathing.
"GINNY!" he screamed, fighting against his invisible chains.
"Dont fret Harry. You're about to join her soon" Voldemort said, "AVADA KEDAVRA." the pain was unbearable, he couldn't breathe, he...
"Shh...Harry, its okay. Its only a dream."
He took a gasp of air and opened his eyes, his scar felt normal, nothing hurt. Most importantly though was that Ginny was here, safe.
Ginny held his head to her chest and was stroking his hair, "Ginny?" he managed through troubled breaths.
"I'm right here Harry. It was all a dream." he sat up and pulled her face to his and kissed her, stroking her hair.
"I'm never gonna let anything happen to you I swear. I love you." he said, holding her tightly.
"I love you too, Harry." she smiled at him, and continued to stroke his hair until he fell into a deep dreamless sleep.
