"Sirius."
"This isn't happening," he murmured to himself as he sunk deeper into the bubbles of the bathtub, suddenly embarrassed to be disrobed before…before his own delusion. "This isn't happening. It's because I haven't slept."
"You can't pretend I'm not here, Sirius." the ghost giggled.
Oh god, oh god, oh god. This couldn't be happening. He couldn't be losing his mind.
"You aren't real." he murmured to himself. "This is just my imagination." he shook his head softly as he grabbed his towel off the floor.
"You can't ignore me Sirius. You certainly didn't try to do that when I was alive…at least not in the beginning."
Oh god, this figment of his imagination even sounded like her. It had only been a few days. Why couldn't the memory of her leave him alone?
"I'm losing my mind." he muttered.
"Clearly, if you're talking to yourself." she quipped.
"Shut up! I'm not going to fight with my own imagination."
A cynical smile graced the lips of the ghost. "Sorry, am I not good enough conversation? Should I do what I'm good at and moan?"
"Stop! Stop! You're not real."
"You wish." the ghost smiled as it faded from his view.
