Hello again! This is an idea I just had, and it may need updating. Let me know if you think it could be more! I'm not too confident in it...

Hiccup awoke to a horrible noise. A high-pitched scream of horror. He looked up, or rather tried to. His head felt like lead, weighing him down and making him feel useless. He knew he had to help.

There was another scream, only this time it was a man's scream. The raw Viking cry sent chills down Hiccup's arms and his back. He knew that scream. It was his father's.

"Stoick!" A woman's voice cut through Hiccup's skull. It sounded vaguely familiar.

"Val!" Hiccup heard his own father's rough cry, followed by a baby's wail.

Why is my father shouting my mother's name?

Hiccup closed his eyes, trying to drown out the sound of his own father crying. His father never cried. The sound made Hiccup cringe.

"A chief feels no pain..."

The words that Hiccup had heard so many times over the years made him confused. Where was he? Why would his father cry now? His mother had died years ago. He had gotten over that.

"Yessss... Feel the pain, darling Hiccup..."

Hiccup snapped his eyes open, but he couldn't see anything.

"Do you see? The pain of your mother's passing? The utter darkness in your father's soul?"

"Who are you?" Hiccup found his voice was still working.

"I am the voice in your little head. I visit you now to show you the pain you've caused."

"Why?"

"You are useless Hiccup. Your whole world is filled with pain and sorrow, and you have made it happen."

Hiccup felt the blood drain from his face.

"Do you not see how much pain you have caused for your father? Every time he looks at you, he sees his darling Val. You are a runt, a mistake. Feel the pain that your father feels."

Hiccup began to cry as the voice whispered, "Feel it, accident... Feel the pain..."

The tears fell faster as Hiccup listened to his father say, "A chief feels no pain..."

"A chief feels no pain," Hiccup whispered to himself. "A chief feels no pain."

The voice sneered. "Don't you know that makes it worse? To know you shouldn't feel the raw, horrible pain, yet you do? It makes you even more of a weakling."

The baby wailed again, and Hiccup realized in horror that the baby was himself.

"Cry little accident, cry," the voice taunted. It seemed to be enjoying this.

Hiccup cried out, "Stop!"

The voice chided, "But don't you see the pain?"

"This wasn't my fault!"

The voice's voice dripped venom. "Your father was left with a child to raise on his own, a child who reminded him of his wife. The child grew up to be a runt, making him unfit to be a chief's son. It caused Stoick so much sorrow, sorrow that you have created."

Hiccup felt anger flare in his heart. The voice was toying with him, trying to get him to break. To give in to himself.

"Get away from me! Just go! Leave me alone!"

The voice laughed.

"Go away!"

"Look at the pain you've caused," it said.

A bright light flooded Hiccup's eyes. He blinked and lifted his head again. His eyes took in the most horrific scene Hiccup had ever seen. His own father, hunched over on the grass, cradling a bundle in his arms. The bundle was crying, and Stoick the Vast was hugging it as if it was the only thing left in his world.

That's me, Hiccup thought, horrified.

"A chief feels no pain," Stoick repeated it like it was the only thing he knew how to say.

"This is the pain you have created. You caused this. Your mother ran into your home to save you. This is your fault."

Hiccup couldn't stop the tears now. It really was his fault.

"Why? Why would you do this?" Hiccup asked as guilt filled his heart.

The voice didn't answer. Instead, it taunted, "Cry accident, cry..."

It had been a dream.

But it left Hiccup scared for a long time.

And now, his own father was dead.

For a long time, Hiccup had only him.

And it's my fault he's dead too.

My fault.

I should have done something. Tried to talk to Toothless. Or somehow get to Drago.

But no. I just stood there.

I let him die.

"And whose fault is that?"

Hiccup stiffened at the sound of the voice.

"Yours."
