A/N: Gonna be basic, Harry has DID (Dissociative Identity Disorder), and Snape finds out. Back in this time (pre-1994), it was called MPD (Multiple Personality Disorder), so until the story gets to 1994, it will be called MPD (probably even further because it probably won't reach the wizarding world for a while.

For your information, I am indeed part of a DID system. I am one of the many Alters of the system (not the host!), and will write whenever I have time in the front. So don't call me out for being inconsistent. I hope you enjoy my story, starting in First Year, while Harry is under the Sorting Hat.

— Chapter 1 —

"Very interesting… interesting indeed." Harry heard a voice say in his head.

'Huh?'

"Ah, yes, hello Harry. I was just commenting on what I see in your head. I see you doing great in Slytherin. It's honestly the only place I can really put you."

'Slytherin? But everyone there is evil!' Harry mentally screamed, panicked, sweat starting to form on his head.

"Do you think yourself evil Harry?"

'What? No!'

"Then not all Slytherins are evil. I can see great things from you here, and many great friends. You will bring great change to the house of Slytherin, all for the better. Do you want me to out you somewhere else?"

'Uhm… no? I'll… I'll go to Slytherin?' Harry thought out.

"SLYTHERIN!" The hat yelled, making him cringe from how loud it was. The hat was picked off his head, and he headed over to the Slytherin applause.

He sat down next to Theodore Nott and Tracy Davis. "Howdy Potter, glad to see you here." Theodore Nott said. "You can call me Theo, nice to meet you."

Harry took the hand that was reached out to him. "Nice to meet you Theo, call me Harry."

Harry then looked back up over to the head table to continue watching the sorting. He saw Ron Weasley glaring at him, and Harry quickly look away.

He saw Professor Quirell, and when their eyes met, his head exploded in pain, and he blacked out.

— Snape POV —

When Potter was sorted into Slytherin, Severus Snape knew some thing was up. There was no way the son of James Potter would ever go to Slytherin. He would have been raised to be the perfect Gryffindor, wouldn't he?

Then, the young Potter made eye contact with the Professor to his right, Quirell. Instantly, the boys eyes widened, and his arms twitched upwards. Then his eyes , prevously looking at everything in wonder, settled into a bored glare, a small frown appearing on his lips. He rolled his eyes, and flinched forward at Quirell, who flinched backwards in suprise, and hit his head on the back of his chair.

Snape could see the raw magic that was thrown at Quirell.

— Later —

When Snape led his new Snakes into the dungeon, giving his normal speech about house unity. He then started looking into each first years eyes, and sending out Legilimancy probes. No one had any defenses whatsoever… except Potter.

There was no built up defenses, but natural. His mind was a maze, with many secrets around. He saw someone who looked like Potter, but with longer, tamer hair, and no glasses.

The boy smirked, and Severus felt a stabbing sensation in his chest, before he was pulled out of the boys mind.

"Goodnight all. You have Potions first thing in the morning, don't be late or else!" Severus dramatically exclaimed, before turning around… and feeling pain in his chest. He felt down, to find blood. He quickly waled out of the room, not hearing Potters chuckle.

— A/N: Should I end it here? It does seem a little short… whatever, I'll continue after a break —

— Potions (Harry POV) —

When Harry's vision and hearing came back, he was in the middle of a class. He dropped the thing in his hand, which fell into his cauldron with a splash. He looked around confused.

He was in Potions class… he saw Snape looking at him with an eyebrow raised, and Harry looked down. He found his book open. He tried to find where he was in the potion, or even what potion he was making.

He found he was making a cure for boils, and had just added the Shrake Spined. He quickly, but gently, started stirring.

Harry found his 'glug of stewed horned slugs' and added them.

Taking the potions off the fire, he added the porcupine quills.

A munite later, he smelt a weird odor, and an explosion. Neville had blown up his cauldron!

Luckily, Harry was on the other side of the room, so wasn't hit by the potion. But Dean Thomas wasn't so lucky.

"Idiotic Gryffindors. I'm taking 20 points for your mistake, and giving you a T for the potion. Get yourselves to the infirmary. Now! Before I take another 30 points!" Snape yelled out, sending Neville and Dean running from the room in panic.

Harry in the meantime, had finished the potion. Snape looked it over, and gave it an 'exceeds expectations', and Harry "five points to Slytherin" while looking directly into his eyes.

Very confusing, but a… decent first class?

The next class wasn't that much better. Herbology was something else entirely. Harry liked plants, but these magial plants? No… thank… you!

Devils Snare. Supposed to snare devils, but acts like a devil instead. It did not like him. Gave him a few cuts on his wrist while trying to strangle it.

His partner, a boy named Blaise Zabini, now exclusively deals with the plant, while Harry writes the results of it's growth.

At the end of the day, Harry was very tired. It makes some sense in his head, he doesn't remember getting any sleep, not to mention he's had a headache since Defense class after lunch. So when Harry got into his room (where he followed Theo and found the plaque with his name), he layed down on the bed, still in his school robes, and drifted off to sleep.

Little did he know, his body wouldn't be getting much sleep that night. There were assignments to do after all.

— A/N: There you go. I hope you enjoyed that, and I'll see you whenever I'm up fromt long enough to finish another chapter. For now though, someone wants to read.

Book Suggestion - 'The Alchemyst: The Secrets of the Immortal Nicholas Flammel' which is a great book that has nothing to do with the Harry Potter universe. —
