"—da? Sir Sawada?"

He blinked twice, escaping his trance-like state. He didn't even realize he was in a bar, drinking a glass of margarita. He faced the man who had been calling him for God-knows-how-long. "Oh, I'm sorry, what were you saying?" Sawada squinted, analysing the man from head to toe. He couldn't remember meeting this man.

"Oh, um, as I was saying, the Gesso family has extended their ties to the Rosso family." The man continued.

Sawada closed his eyes, calmly breathing in and out. He knew there was something off, and he had an inkling of what it was.

"There are two reasons why people enter the minds of their targets." Reborn told him, during their tutorial sessions in the Vongola mansion's private library. "First," he raised a finger, "is to steal ideas from another, and second," he raised another finger, "is to implant ideas or an idea in the target's subconscious."

"What is your point, Reborn?" his fifteen year old self asked, a bit confused at the current topic.

"My point is, Dame-Tsuna," he pointed a gun on his student's temple. "Anyone can enter your subconscious. It is essential for a mafia boss to be able to protect himself from these kind of attacks."

"But, to enter another's subconscious?" Tsuna smiled at the ridiculous idea. "Isn't it impossible?"

Reborn smirked, "then tell me, Dame-Tsuna, where are you right now?"

The brunet blinked twice, "I'm in the library, of course!" he replied, smile turning to a frown.

"But, how did you get here?" Reborn's second question made the Vongola Decimo freeze. "Now, it's time to wake up." The baby pulled the trigger, and the Vongola Decimo woke up from his sleep, only to be confronted by the annoying face of his tutor.

"And that, Dame-Tsuna, is one way to wake up from a dream."

Ah, It finally sunk in. It was all a hoax – a dream. Now, where's Mukuro when you need him? His lips pulled up to form a smile. Mukuro was, after all, one of the few people who entered his dreams without permission, claiming to 'look at how corrupted' his mind was.

"You're the dreamer aren't you?" the stares of every person in the room were directed at the man talking to him. Sawada smiled as he saw the man freeze.

"W-what a-are you t-t-talking about, Sir?" the man asked, growing nervous from all the stares directed at him. He gulped when he saw the bartender take out a bazooka, the waitress a set of knives, and a few customers an AK-47. And there and then, he fainted.

"Technically he's not dead yet," Sawada peered at the unconscious body. "Nice job on the illusion, Mukuro," he grinned at the bartender.

"And here, I thought you were set to believe that this was reality." A body of mist surrounded the bartender, turning him into Rokudo Mukuro. "Too bad," he sighed, "so should I kill you and this man, now?" he asked, with a hint of mischief.

"Well, I don't know when I wake up, so go ahead."

"You only say that so I can have the joy of killing you, even if it's just a dream…"

"But, you enjoy it, nonetheless." Was Sawada's reply before Mukuro plunged his trident straight through his chest, "See you later, Mukuro." The Vongola Don's body fell limply on the ground as Mukuro pulled back his bloody trident.

"Kfufufu, see you later, boss."

Author's Note: Inspired by Inception. I'm planning on doing a fanfic crossover between KHR and Inception, but , of course, I need to finish my other fics as well. So, once I finish my "Vongola BAU" and once I get accurate and precise information (with the side of re-watching Inception a lot of times), I'll publish a crossover fic (hopefully). Now, I have to get back to studying for my exam tomorrow. =_=. (I still don't get why I wrote this in the middle of the night when I have an exam tomorrow… huh…)

Please review :3 Feel free to say anything about the fic, I guess.
