A nightmare?

In the dream, Bakugou felt like he's falling into a different world. Everything was surrounded in the haze of darkness. Then he saw a figure walked toward him. That's a man in a black suit with no visible nose, ears, hair, or eyes.

"YOU!"

Bakugou recognized that man: All For One, the most powerful villain in history, and All Might's arch-nemesis, the one who kidnapped him.

"Explosive boy, I'm glad that you still remember me."

"This can't be real. You are being imprisoned in Tartarus. There's no way you can use a Quirk to invade my mind."

"You know what people said 'no cage can imprison imaginations'. It's just that I'm sleeping and our dreams collide."

"I don't believe anything from your mouth. What do you want from me?"

"Nothing. I don't want to harm you."

"Don't want to harm me? You fucking give me a disease that the world never heard of!"

"It's not a disease, but a gift. That's enough for today, I'll return when you understand what I mean."
