Pyros sighed heavily, leaning against the wall next to an antique shop. Quiet zombie groans emanated from inside, but they didn't seem to have noticed him yet. For a trip through an undead-infested mall, his stroll had been pretty uneventful so far.
"I need a weapon, though," Pyros scowled. "I'm sure I could find something in here. Take off a table leg or something."
His mind made up, Pyros yanked off his trench coat and held it in one hand as an impromptu weapon, leaving him looking a lot more normal in jeans and a black t-shirt. Brandishing the heavy milk-carton-laden garment, he advanced into the shop.
Without warning, a pair of clammy hands fastened around his neck from behind. Foetid breath blasted past Pyros's head as the zombie behind him groaned loudly, "BRAAAAAAAAINS!!" Unable to swing the coat at a target behind him, Pyros settled for throwing himself backwards, ramming the zombie into a display of antique chairs, impaling it. The hands released his neck, and he stumbled away from the zombie.
"CHAAAIR ZOMBIEEEE!!" Pyros turned quickly as the creature struggled to its feet, two chair legs sticking clean through its body. Dragging the chair behind it, the zombie advanced on him, laughing, which came out as an ugly rasping noise. "Ha ha ha, chair zombie... CHAIR BRAINS!" The thing was very clearly off its rocker, and not even recognizable as having once been human. It was also, apparently, indestructible, as Pyros found out when a swing of his coat failed to do more than leave a dent in its already deformed head. A tiny drip of milk from a lower pocket told Pyros that at least one carton was damaged, but he didn't have time to deal with that.
Crud, what do I do now? Pyros racked his brain as the zombie drew closer. A wall behind him, and two tall shelves to his sides, left Pyros trapped. Boy, am I screwed.
~Nah. There won't be any screwing going on until I say so.~ Pyros frowned at the odd thought. It's a bad sign when you don't know what your own mind is talking about, right? And the dauntless zombie advancing on him made this a very bad time to have a conversation with himself.
~Oh, don't worry about that, just sit back and let me take over.~ The thought seemed to be a response to his other thought, and Pyros began to notice a difference between the two voices in his head.
Crud, I really am crazy.
~Nah. Now be quiet and let me concentrate.~ Pyros, seeing no better course, obeyed, letting his mind go blank.
A visible shockwave flew out in all directions from Pyros's body, knocking down the shelves to his left and right and covering them with flecks of pale green slime. The zombie ahead of him disappeared back into the wreckage of the chair display, followed by a loud thud as the entire tangled mass struck the wall. The impact dislodged something hanging above the service counter, sending it clattering onto the glass. Pyros, feeling dazed and confused, wandered over to the table and picked it up.
~Ooooohhh....~ Pyros thought to himself... before realizing the thought wasn't at all like him.
What the-? Why 'ooooh?' His gaze went to the long thin scabbard in his right hand, and immediately Pyros brought his left hand to his forehead with a loud smack.
"No," he said firmly, out loud, "I am not going to bring a katana with me as a weapon. That's just stupid."
~But I want it.~ Pyros scowled, shaking the thought away, and tried to put the sheathed sword back on the counter, but his hands wouldn't seem to obey him. Instead he watched, aghast, as they started to thread the swordbelt through the belt loops on his jeans.
"What the hell am I doing?"
~You're doing what I want, because you're a gentleman.~ The voice in his head was followed by a distinctly female giggle. Pyros's eyes bulged as he realized for the first time that he wasn't alone in his skull.
Gentleman, my ass! He thought angrily. Who are you? Pyros could now tell the difference between the two voices, which was something, he supposed.
~Oh, now he finally gets it! Good for you, Pyros, it only took you a day and a bit to notice there was a ghost in your head!~ Applause rang between his ears, and Pyros gritted his teeth. Ghosts were creepy enough without being annoying on top of it.
Well, now that I've noticed, get out! He snapped, all patience gone.
~Nah. I like it here, I think I'll stay. Though it is rather poorly kept.~ Pyros, with mounting alarm, heard the scratching noise of a broom somewhere between his ears. The ghost girl giggled, and began whistling. ~All your mind needs is a woman's touch,~ she told him teasingly. ~You should thank me for the free housekeeping service.~
Out! Pyros was frantic, wondering precisely what it was that this crazy ghost girl was sweeping away. His rational thought? His free will? His milk cravings? That last filled him with horror and fear, which was met with another giggle.
~I was joking. I don't really have a broom up here. Honestly, if you're so easy to tease it's going to stop being fun!~ Suddenly, Pyros felt completely overwhelmed. There was a ghost in his head, an irritating female ghost, and he foresaw no way of getting rid of her short of hiring an exorcist-- which she probably wouldn't let him do, considering that she could apparently take control of his body at will. Pyros slumped to his knees, despairing.
~Oh, cheer up. Since you obviously can't think of fun things to do on your own, I'll help you! Let's visit some restaurants! I've forgotten how food tastes, and all that milk you carry around hasn't helped.~ Pyros sighed and got up. "I suppose I should be glad you're not just taking control and walking me there yourself." He had really disliked the sensation of being unable to control his own limbs.
~Why should I do the work? You're the human here, it's your body.~ He was prepared to argue when he felt the ghost girl's attention shift suddenly. ~Ooh, kitty themed restaurant!~ Pyros's hand rose on its own to point at the large sign proclaiming, 'Kitty Treats... For Humans!' which rested above a sickeningly cute plastic statue of a giant kitten.
Pyros sighed again and changed course to make for the restaurant. He just hoped that neither actual cats nor his brains were on the menu. Are you sure we have to go there? He asked the ghost pleadingly.
~Absolutely,~ was the stubborn reply. ~I like cats.~
"I'm allergic." Pyros said, stifling his third sigh in as many minutes, and searched for a change of subject. "Hey... you never told me your name. I can't just keep calling you 'ghost girl,' now can I?"
~Oh, right. I forgot you can't read my mind like I can read yours.~ Her tone indicated that she hadn't, in fact, forgotten, and was just taking the opportunity to rub it in. ~I'm Ciara.~
I'd be lying if I said, 'pleased to meet you,' Pyros grumbled inwardly. His only response was the distinct feeling that Ciara was grinning at him. Muttering about rude ghosts who just barged in and made themselves at home in your brain, Pyros walked into the Kitty Treats Restaurant.

Fear me.
