Intruders

Izuku knew he was dreaming. It was a nudging, lucid feeling in the back of his mind. He knew none of this was real. Well, maybe real, but not external. There was black mist covering his entire body from his nose and below, and part of him wondered how he was breathing, or if he was breathing at all. His surroundings were borderline psychedelic, with purple and blue spirals, some golden squiggles, and puffy pink clouds. Speckles of orange danced around the air(?) and six figures materialized around him. It was like he was being sacrificed to some sort of LSD god.

He tried to talk, but the mist soaked into his mouth. The yellow figure shook her head. "Don't speak," she said. "You're considered an intruder here. Defense mechanisms will kill you."

Izuku furrowed his eyebrows. How the hell could he be an intruder? Not only did he not know where he was, but he also wanted to get out.

The gray figure stepped forth. "We're running out of time," he said. "None of this is your fault, not really. It's us to blame. We were just trying to protect him."

His poor explanation only made a million more questions blossom on Izuku's tied tongue.

The green figure stepped up, too. "It's better if we just show you, yeah?"

Izuku couldn't respond. He was pushed backward, off some sort of diving board. He was falling for minutes, or maybe hours, maybe even days before his back hit a pool of water and he submerged into the darkness.

It was all a dream, he told himself. But everything was so disturbingly vivid.  

He was in his usual seat at Yuuei, sitting behind Katsuki. His notebook was in front of him, and a pen was tight in his hand. His eyes were aimed like lasers up at the board where Mr. Aizawa was droning on about work studies. He didn't have a very good speaking voice when he was tired, but Izuku always knew to cut the man some slack. He was overworked and underpaid, and yet he still showed up to work every single day without fail.

The minutes ticked by. Aizawa kept talking. Sato was snoring. And Ojiro was kicking the back of Tokoyami's seat. And Iida was about to burst a blood vessel because Kaminari was playing a game on his phone under the desk. And Sero kept making tiny tape balls and throwing them at the ceiling to see how many he could stick up there without anybody noticing. Mina noticed, and she was fighting back her laughter, especially when one fell into Hagakure's hair. She thought it was a spider and ended up a sobbing mess, her noise muffled by Kirishima, who was trying to make sure Sero didn't get in trouble.

The whole thing was ridiculous and completely in character, Izuku thought. He wanted to laugh along, maybe kick the back of Katsuki's chair to piss him off or something. Unless he was back in his own reality, then he'd get Kat's attention just to see that "annoyed" smile. Kat was so patient with him but also so strong and absolutely hilarious. (They had the same sense of humor, which was really Izuku's favorite thing about the boy.)

Izuku had made friends with Deku's Kacchan, despite his strange angry ways. But he missed Kat. He missed the feeling of his best friend's arm slung over his shoulder, the scent of the cologne he wore everyday that his dad got him for his birthday. He missed ruffling Kat's hair, and in turn having his own hair ruffled. He missed beating the living shit out of the bullies back in middle school and missed chasing the hero/vigilante dream.

Most of all, he was planning on finally telling Kat how he felt. He was going to confess, literally right after the bell rang. But when it did, he was transported months back in time to a completely different reality. He missed the anxiety building up, the urgent tapping on his desk, the mumbling under his breath that only dribbled out when he was in the panic zone. It was better than this fucking homesickness. Izuku sought it more of a disease.
