I didn't know how to react what I'd just do. I looked at my sister, Bill and the guards and after a while I started laughing. Yes, laughing. That situation made me laugh when I'd discovered the truth. Bill was clearly confused. The guards apparently weren't care. No wonder why. They just cared about money. My sister, taking advantage of opportunity, pulled away from Bill and went to me.
"What?" said impatient man, "What are you laughing at?!"
"It's just…" I said with smile, "…you would never take over the world with this!" and I laughed again.
Bill was angry with me, his face became mad. He started breathing loudly. He went to me and screamed, "What are you talking about?!".
I stopped laughing and I became serious then, "I've just used it."
"What do you mean?" asked Mabel, "You… touched it, and then something weird happened…"
"I've been rejected." said Bill, "But you didn't even touch me."
"And then you just stood up."
It looks like, I'd been creating the dreams for only a while. Very strange, but I hadn't been thinking about it many time. I started explain them what exactly happened and why The Energy was useless for Bill. With each sentence I said, Mabel's face was more surprised and Bill's face was more disappointed and angry.
"So… all of those dreams… were created… by you?" my sister asked.
When I confirmed she said, "Woow… That's awesome!"
"No!" screamed Bill, "It can't be true!" and he grabbed me and started shaking, "You're lying to me! Said you're lying!"
"Hey! Let him go!" shouted Mabel.
The guards eventually reacted. They grabbed Mabel's arms and they didn't let her go.
"But it's true!" I said to Bill, "So let me go!"
And he did it. But he didn't calm down. He looked at the grass and noticed purple rock on the ground.
"I…need…it!" he sounds like mental guy. He was trying to get The Energy, but I blocked his way.
"Don't do it, because you ruin everything! Stay back from this!" I grabbed him, but he was strong. His anger and greed added gave him strength. I wondered what to do. If he had got The Energy, he would have create new dreams and change everything. Everything what had happened for last time. Mabel was still grabbed, but she was shouting, "Dipper! No! Don't let him get this!"

And then I felt vibration. Strongly vibration coming from the forest. After a while I saw something. It was a creature. It was a manotaur. But not only his. On him there was also my grunkle Stan. He was sitting on the manotaur like a rider on the horse. My uncle was very excited.
"Beware folks! I've got a minotaur!" he shouted.
"I'm MANOTAUR. " corrected him the creature.
"Ok… So, beware folks! I've got a manotaur!"
And after him, I saw another manotaur with Soos. And another… and another… There were so many beasties and they were running into town. But Stan and his creature were running into our toward. After that I could see also many bunches of gnomes, some gremloblins, flying bats and such more! All of them decided to help us. I was so happy. Bill was scared so I quickly went to the place where The Energy was and kicked it. The rock jumped away and disappeared in grass. After a while I noticed Stan, Soos and two manotaurs behind me.
"Don't touch my great-niece!" said Stan to the guards. He jumped away from the creature and moved to them. One of the creatures looked at the guard and grabbed him by neck. Immediately, he snapped his neck. We heard loudly crash and the man fall down on the ground. Another guard let my sister go and said, "What do you want for me?! I've just been doing what I was told!" he was scared, "Please let me go. I don't want to have anything to do with this!" and he run away. Nobody decided to run for him.

And then we'd noticed there wasn't Bill with us…
He ran away too. He ran away, but we hadn't noticed where.
"No!" I screamed, "Damn it! Bill, where are you?!" I was so angry I didn't saw him when he stood up and ran away.
"Don't worry little guy!" said one manotaur. "We'll find him!" and they went into forest. But before they disappeared I said to them, "But don't kill him… Catch Bill and bring him to me." Others were quite surprised when they heard my words, but they didn't oppose.
I looked at my device. The machine said 06:15:10. Whatever, I would had to go back to dream anyway. That war would take long time.
"What are we going to do now?" asked Mabel.
"We have to expel all the guards." said Stan, "And then we can wake up the whole town" and he looked at me, "You were right Dipper, we can't involve the residents in this mission. We can't wake up the town, until there will be safe here"
Stan agreed with me. I was glad he did it.
"Let's go to the center of town" I said to everybody, "Probably they're fighting right now. He have to help them. Specially the gnomes… There are quite small. It's easy to… crush them."
Mabel laughed, but then she'd realized there were nothing to laugh.
"Is everybody have a weapon?" asked Stan and me, Mabel and Soos took out our axes from our pockets.
"Yes…" we said together.
And we went to the center of the town.
I could imagine that view when the fight would end. So many dead bodies, so many blood and disasters… I wondered how long would take the people to reconcile they had been sleeping for so long and how long would take the people to repair Gravity Falls. Mabel had worried and sad face.
"Don't worry Mabel" said Soos to her, "It's almost end. We can handle with it!" and smile to her. After few minutes we were in the center of Gravity Falls.

The view was terrifying. Creatures from the town and the guards were fighting. I heard screams and the sounds of breaking bones. A lot of blood ran down the ground. Many dead bodies were lying on the ground. And indeed, some gnomes were really crushed. A lot of manotaurs were dead, but they had been fighting very hard. I'd noticed also some guards didn't want to fight, they were screaming they apologized and they hadn't even kill anyone. Those men ran away and other creatures didn't run after them. However, most of them preferred to fight. I couldn't look at another falling on the ground bodies. I knew it would have to end as soon was that possible, so I decided to go and kill other guards.
"Hey, what's up?" I asked with smile one of the manotaurs who was fighting with one of the men.
"Great! A lot of fun!" he answered and laughed.
"Dude! Look out!" screamed Soos. I turned around and I saw the man with a gun. He immediately put his gun to my forehead. He almost pulled the trigger, but then he had been pushed. He dropped his weapon on the ground and he fell on the ground. The person who pushed him was my sister. He had an axe in her hands. Mabel lifted her weapon and plunged it into his stomach. She looked at me and smiled, "Ok… Is something wrong with me? I've just killed a man with smiled" she said and laughed. Maybe I was insane too, but I smiled too.
"Hey!" Mabel yelled to everybody, "We don't have to fight! Just leave our town!"
Almost nobody reacted. Some people dropped his weapon, but most guards didn't stop fighting. On the downside, more guards came out from the buildings and started shooting from their guns.

I don't know if talking about men and creatures fighting makes sense. It took a long time, it took a lot of bloods and took a lot of lives. Sometimes, we had to run away from the places where we actually were and go hide, because in some places there were too much guards. I didn't excepted there could have been so many guards in the town. When I'd noticed it started to get dark I looked at my device.
00:04:53
"Uh-oh, four minutes" I said to my family and friend.
We made sure we were in safe place and everybody pressed buttons on our devices and we went back to our dreams.
Not much to talk… We were in our dream for the last time. We've just waited with impatient for one hour. It had been probably the longest hour in my live… I spent some time telling Richard and Nancy what happened in real Gravity Falls. They were completely shocked, but they were also pleased we had chance to save the town.
One hour passed…

We woke up from the dream and looked at the town. Everywhere was quietly… I couldn't see anyone. Well, it was night so no wonder, but there were no one. We went to the Gravity Falls center. No one again…
"Where are everybody? " asked Soos.
"Did they killed each other?" said Mabel.
"I have no idea" said Stan.
And then I felt vibration. The same vibration I had felt when manotaurs were coming. And I was right. I saw manotaurs and other creatures from Gravity Falls who were coming to us. They were stained with blood and dirt. Manotaurs were walking slowly with serious faces. When they came to us one of them said to us, "It's the end…"
"Do you mean… " started, but he interrupted me.
"I mean… all of the guards has been killed. Except some people who decided to leave the town."
So it was end… I could not believe… it was end… I was supposed to be pleased… So why wasn't I happy? I looked around and what I saw? Sleeping people from the Gravity Falls, dead bodies, ruined buildings, blood everywhere…
"Hey" said the manotaur, "It's not all, look who were we find!" and he moved.
Between two manotaurs I'd noticed a human. It was a person I'd known. It was Bill.

He was so scared. He looked at us and tried to make us pangs of conscience.
"Please… " he was almost crying, "let me go… I'm sorry."
I went to him and looked at him. His expression didn't make me feel. I'd noticed a dead guard, so I moved closer to him, leaned over to him and took his gun. It was small, silver gun. I looked at the weapon and looked at scared Bill. He was breathing loudly.

Now…I don't know what I would do, but that day I was sure what to do. If you think I had been broken, had forgiven him and all lived happily ever after like a fairy tale for children, you're wrong!
When I was looking at him I recalled about Wendy, her dad and whole destroy town I was so angry with him. I put the gun to his forehead and said, "Sorry, but it's necessary."
And I pulled the trigger. By recoil I moved back. On Bill's forehead big, red hole appeared. Blood was coming out from his head. I dropped the gun on the ground and moved back.
I turned to Mabel, Stan and Soos and said with seriously, "And this is over…"

And that's how my adventure ended.
After few minutes my sister recognized me it was time for wake up the town…
"Yes… You're right. Let's go." I said to her and we ran to the building.
"Do you have this bomb still?" I asked my great uncle.
"Sure, here you go." And he gave me the little cube.
We destroyed the building and went inside. We were thoughts the corridors and doors and went to the room with power.
But before I turned off the switch my sister said something to me.
"Dipper? What we're gonna do after that?"
What we're gonna do?...
I didn't need take much time to wonder.

I smiled to her and she smiled to me, "We're going to discover other creatures and fantastic mysteries of the town! We're going to enjoy the rest of the summer!"

And I pressed the switch.
