I opened my eyes. I was laying on something undecidedly solid, surrounded by darkness. But there! A flash!
Suddenly I saw it all- thousands of multi-coloured lights threading their way through darkness at super speeds, so fast your brain can barely register them before they disappear. It was an astonishingly beautiful sight, but I was too confused to admire astonishingly beautiful sights.
There was a shadowy figure in the distance.
"Hello! Where am I? How did I get here?" I called.
The figure came closer. It was my nerdy friend Arthur. I had no idea what he was doing there, but I was glad that he WAS there.
"By my reckoning, we have travelled through the point of singularity in a super-massive black hole and arrived in..." my nerdy friend Arthur checked his watch, "well, I'd say... about the 5th dimension."
"What does that mean?" I asked.
"Well," my nerdy friend Arthur said, picking his words carefully, "we don't exist."
"I exist!" I said.
"So you do," my nerdy friend Arthur replied calmly, "If that's what you'd like to think."
"I do! And so do you!"
"If you think so, then I'm sure I do."
"What do you mean?"
"Cognito ergo sum- I think therefore I am. Consciousness is the only proof of existence."
"What?"
"You only exist," he explained patiently, "If you think you do."
"Well, I think I exist."
"You must be real then. The thing is, you see, that the other one of us is possibly a fragment of our own imagination."
"So you're saying that you're imagining me?"
He nodded, "or you me. Either way, it doesn't matter. It's all the same."
"But I don't want to imagine you; I want you to be real!"
"And I am, to me. But I might not be to you."
"Oh, I give up. What are those lights?"
"Universes," he stated matter-of-factly.
"They're beautiful!"
"I've been here before- they get boring after a while."
I couldn't be bothered arguing. Time for a quick change of subject. "How do we get out of here?" Beautiful as this place was, I was getting hungry. Stomach over mind over matter.
"We don't. Not for a little while yet, at least."
"Why not?"
"We're in the 5th dimension, the dimension that controls all of the major aspects our home dimension, the 3rd."
"So what?"
"So, from this point, we can control anything we want in our home dimension."
I looked at him. He was standing resolutely, his shoulders set back in a look of stubborn purpose.
"So you're saying..." I began.
"Yes?"
"That we're here..."
"Spit it out!" he snapped. Something was wrong. He never snapped.
"To change something back home?"
"Finally!" he clapped, sarcasm dripping from every syllable, "the half-wit gets it!"
"Wait, so you brought us here on purpose?!" I looked at him in disbelief.
"Yes, partially. I came here to change our home reality slightly."
"What are you going to do?"
"Make myself a god."
I stepped backwards. Slowly. My brain was fogged up with the enormity of this revelation. "So there are such things as gods?"
He smirked, "There will be."
His statement started to seep through. Make himself a god. Wait a second, he said... oh. MAKE HIMSELF A GOD!
"No." I said quietly.
"What as that?" he leaned in closer.
"No!" I yelled, "I won't let you!"
"I'm sorry," he said, looking rather bemused, "you don't have a choice."
"Why did you bring me along then?"
"I didn't. It was an accident. Total freak of nature."
I stood and thought about this for a while. My brain was crystal clear now and racing faster than a bunch of Formula One race cars. What could I do? The answer was simple, like me I suppose: stop him. But how?
Arthur had activated his computer, and had brought up a compressed model of the universe. I didn't understand the situation fully, but I did understand two crystal clear facts: one, I had to stop him somehow. Two, he was an arrogant bastard and I should have seen it earlier.
I thought back to our most recent conversation. Hmmm... What had it been about? Oh yes, that's right, existence.
***
A note should be noted at this point. It is important to understand that the universe is BIG. Though BIG is an understatement, I will use it for the sake of simplicity. Now, you must understand that compared to the universe, the 5th dimension is HUMONGOUS. Though HUMONGOUS is understatement, I will use it for the sake of simplicity. Because of the HUMONGOUS nature of the 5th dimension, my brain was mainly busy imploding at the sheer HUMONGOUSness of it. It is so HUMONGOUS, you can't describe it. The small section of my brain that wasn't busy trying to find a way to slide out my ear was trying to figure out a way to stop Arthur, which was why I was taking so long. Most of you have probably already figured it out by now.
***
I wondered briefly why Arthur wasn't feeling the same effects that I was. What had he said?
"I've been here before."
That was probably why.
Anyhow, back on subject-hmmm... how to stop him... existence! He only exists if I think he does! So if I don't think he does, then he doesn't exist! Problem solved.
I cleared my mind in the same way I had taught myself in Math lessons. Drift out of focus.
Only one thought remained- this is a dream. I'm dreaming. Arthur is a dream. He always has been. Then- what Arthur? There never was an Arthur. Except for maybe King Arthur of Camelot. No, no! Stop! No Arthur of Camelot either. The last thing I need is to have Arthur as a king of a bunch of knights. Then- what knights? It's all a dream. A DREAM. Arthur is gone. This isn't him. It's a DREAM.

A dream.

...

I opened my eyes. I was lying in bed. In my bedroom. In my house.
It was morning, and the sun was filtering in. Just a perfectly normal morning.
Mum came in, "How'd you sleep, sweetie?"
"Pretty well."
I had a niggling feeling that something important had happened. Must have been a dream.
"We're going to Camelot today," said Mum as she walked out of my room, "to pay our taxes to the Knights."
