Gohan was shocked. More than that, his heart was broken. His heart wasn't this torn since he watched his father teleport away with Cell. He could spend some time questioning his feelings but now wasn't the place for that.
"I don't understand, Twilight. A nightmare?"
"It's Princess Luna's domain. The world of sleep, that is. The Tantabus was something she created and had complete control over but now it's free. Somehow. And it came from my dream. Celestia thinks it has to do with her visit to me in the night. When I was dreaming about your world."
Goten stepped up. "But that doesn't make any sense. Mom always says that nightmares aren't real."
"They're not, Goten," Twilight said, "but the Tantabus can be real. It was holding it off together that threw her into this sleep that she cannot wake from."
Goten jumped up in the air and began to hover "Let us help you beat it up! We can take it down no problem!"
Gohan hissed through his teeth. "Goten. Hush. This world doesn't work like ours." Gohan lowered his head and bowed to Celestia and Twilight. "I'm sorry for causing you trouble. I will not return."
Goten fought Gohan the whole way back but he was able to push him through the portal with ease. Then he looked back to Twilight one last time before walking through the portal himself. That would be the end of his friendship with Twilight Sparkle. At least, it would be for the time being.
A month of time passed and a new terror had arisen and been defeated. A terror known as Majin Buu. All memories of the event were erased except for those who joined in the fight and during the chaos of the fight, Goku, the father of Gohan, had been brought back to life.
Now Gohan slept in his bed that he shared with his younger brother, having long given up on his chances to meet his friend Twilight Sparkle again, but having not forgotten her face as she entered their world and he had helped her to stand. Something about being forced away from her rubbed him the wrong way but he wasn't sure what he could possibly do about it.
Little did he know that his adventures in Equestria were not over as in his dreams, a hellish nightmare attacked him. One that replayed his mistakes against Cell over and over and had his father express disappointment in him. The look on his father's face was the worst part of the nightmare along with the words his dream father spoke to him as Cell destroyed the planet.
"You've failed Gohan."
"Gohan" He had heard in his dream from a new voice. One that he did not recognize.
"Gohan listen to me, I am here to help." Gohan looked to the night sky and the full moon and from the moon came an alicorn princess. A navy blue one with a flowing blue mane and tail.
As Gohan stared at her, his form was returned to that of his teenaged self and not of that of the child who fought against the monstrous android. "You're… an alicorn princess." Luna used the magic of her horn to blow away the scene, leaving only the disappointed form of Gohan's father in their dream world of stars and bridges of light.
Luna smiled and nodded. "That I am. I am here to help you. This nightmare you have is no ordinary one. It is one that is tainted by a Tantabus."
"Tantabus…" Gohan's eyes grew wide. "That's the monster that put the princess, Luna, into a coma! Wait, she was the princess of dreams, wasn't she? Does that mean you're…?"
"I am her. The princess of the night, Luna."
Gohan swallowed nervously, something about this meeting felt spooky to him. This pony was supposed to be out cold right now, wasn't she? Then again, it had been some time since the incident, maybe she was healed.
"You are wondering why I am here."
"Actually it's more like, are you okay?"
Surprised by his worry of her, Luna blinked a few times and then smiled softly. "Truly you are a good friend of us ponies. I am still trapped traveling from dream to dream, trying to find my way back to my own. I am forced to follow the path of the Tantabus, only, it's not alone."
"The… Tantabus…?"
She nodded. "Yes. That man whom told you your greatest fear is actually the Tantabus in disguise." Using the magic of her horn, Princess Luna shown a bright light to reveal the Tantabus' true form. A hideous cloud of dark smoke that flowed throughout the dream.
"Whoa! Wait, how do we get rid of it?"
"It is being controlled by one who stole my necklace. The necklace which kept my control over the dream world. The one who shall soon arrive here."
"Have you been running from that person this whole time?"
Luna nodded again. "Correct. I have been waiting to find someone to aid me in my fight against them. My sister's strength was not enough. I had hoped to run into Twilight Sparkle and her friends so as to combine their dreams and to defeat the creature who stole the Tantabus from me as we defeated the Tantabus itself long ago. I did not expect for it to connect itself to you and your dream."
"Yeah, that…" Gohan rubbed his head, "that's really confusing, isn't it? Why would it have access to me? I'm from another world."
"I, too, wonder the same thing. Perhaps now that you have entered both worlds, your dreams have become a bridge to them."
"My… dreams?"
"Dreams connect us all, Son Gohan."
"Wait - you know my name!"
"As I said. Dreams connect us all. I knew of your name the instant I entered your dream. You are now just as much my subject as all of the ponies in Equestria."
"A-hah… right. Okay. Wow. That feels weird being told by a pony that I'm their subject."
"Hmm.. is it?"
"Yeah - well - anyways, are you sure you want my help? I failed to defeat Majin Buu twice. How could I possibly defeat whoever gained control of this Tantabus thing?"
"Majin Buu? No matter. I sense a great power within you, Son Gohan and I know all about the feats you have completed. I've seen it through your dreams. I know it must not have been enough to defeat this opponent you mention, but you are more than powerful than all of our alicorn prowess combined. You are the one who must help me defeat this foe."
Gohan swallowed nervously. "Alright. I'll do it. Do we just wait here or….?"
Luna nodded but before she could open her mouth to speak, a tear in Gohans dream broke through and out of it came a creature he never expected to see.
