Sonic had a dream that night. He was outside a building with a nice, green lawn & well-pruned bushes. Near the entrance stood another Sonic. This one looked different from our Sonic because it had an almost perfectly-round head (barring the quills on the back, of course). Sonic approached the other Sonic.
"Welcome, little boy, to Sonic's Schoolhouse!" said the other Sonic in a high-pitched voice. Strangely, this Sonic's mouth didn't move when he talked, always having the same smile on it. This Sonic never blinked, either.
Anyways, the other Sonic continued: "…I hope you enjoy your stay! Eheeheeheehee!"
"Wait…I have my own schoolhouse in this dream?" queried the real Sonic, puzzled by the whole setup. "And you're ME!? Actually…this could be pretty neat!"
"What's your name, boy?" asked the other Sonic. "Is your name Sonic?"
"Right on, man!" replied Sonic. "How'd ya know?"
"Because my name is your name! Now, welcome to Sonic's Schoolhouse!" The other Sonic led the real Sonic inside. The floor had gray & dark gray checkerboard tiles. The walls & ceiling were white. Additionally, the walls had posters of Sonic & Tails.
"Actually…this is pretty neat!" remarked the real Sonic.
"It is pretty neat!" said the other Sonic. "Why don't you go take a look around?"
"Well, I always thought school was pretty lame, but I think I'll dig the scene!" The real Sonic walked around and looked at the various doors. "Now, which one of these doors should I go through first?"
"Try that one!" The other Sonic spontaneously appeared from behind a door with a bunch of letters on it.
"OK then!" The real Sonic entered the room and discovered a bunch of bouncing letters & some chalkboards.
"Wait a minute, what's this?" wondered the real Sonic. "This is freaky-deeky!"
"Oh, that's nothing!" said the other Sonic. The real Sonic exited the room and tried another door. "Now, this is a door!" said the other Sonic, who again opened the door from behind. "You'll enjoy this one, I assure you!" This room also had chalkboards, but it also had some multicolored balloons with different pictures on them.
"OK, this is just too much of a trip for me," said the real Sonic. "I'm outta here!"
"Oh, you can never leave!" said the other Sonic.
"Whaddaya mean, I can never leave!?" retorted the real Sonic. "Of course I can! I'm outta here!" He attempted to open the door, but it was locked.
"You can never get out!" The real Sonic kept trying to open the door, even trying to spin dash his way out. However, the door held tight.
"What's the meaning of this!?" demanded the real Sonic. "I wanna get out of this joint!"
"You don't have to worry, Sonic!" assured the other Sonic. "Everything will be fine! Just sit back and learn!"
"But I don't wanna learn! This is just too much of a trip for me! I want out right now!"
"You'll never leave, Sonic!" said the other Sonic, or maybe we should say "Nightmare Sonic" from now on.
"Come on, there's gotta be a way out!" After a few moments, the real looked at the blackboards & the balloons. He noticed that the blackboards had words like "ASTRONAUT" & "CONVERTIBLE", which led him to the conclusion that he had to match the balloons to the correct blackboards. So, the True Blue Hedgehog went around frantically trying to match the two. After a minute or so, he completed the challenge and raced out the door.
"In your face!" exclaimed Sonic, who rushed to the backyard. He was just about to jump the fence when the gate opened for him. It was Nightmare Sonic again!
"Watch out, Sonic," said Nightmare Sonic, "or Robotnik will come and get you!"
"What, Robuttnik's here too!?" exclaimed Sonic.
"YOU CAN NOT ESCAPE, SONIC!" Sure enough, the Doctor was there in the backyard, chasing Sonic around in the Eggmobile. "You will be trapped in this place FOREVER! HA HA HA HA HA!"
"Oh no, I ain't rottin' away here!" retorted Sonic. "I'll find a way out soon!"
"There is none!" said Robotnik.
"That's right, Sonic," said Nightmare Sonic, "There's no way out! Now let's learn!"
"We'll see about that!" said Sonic, who jumped up and kept hitting the Eggmobile until it was heavily damaged.
"You may have won for now," shouted Robotnik as he flew away, "BUT YOU'LL NEVER GET AWAY!" Sonic jumped the fence only to land in another part of the backyard.
"YOU CAN NEVER LEEEEEAAAAVE!" taunted Nightmare Sonic. "Just go back inside, OR I'LL KILL YOU!"
"You can't kill me!" retorted Sonic. "This is only a dream! Just a really…bad…dream…" Sonic trailed off when he saw his next challenge: one of those Concentration games. Here, there was a group of question marks arranged in a circle. When Sonic activated one, he activated a hologram of himself. The next one he activated was a hologram of Bunnie. So, after failing to get one match, Sonic frantically rushed around trying to match all the holograms. After a couple of minutes, he got them all.
"Got it!" exclaimed Sonic. "HA HA! Smell ya later, fake-face!" Sonic bolted for the front door.
"You may never leave, Sonic!" said Nightmare Sonic. "There's no way out!"
"Oh yes there is!" retorted Sonic as he bolted through the front door. "Ya snooze, ya lose!" Sonic kept racing on until he got to a city. In the city, he waited until a bus came around. He got in, paid the fare and took his seat. The bus was filled with a variety of humans & humanoid animals such as himself. The driver, an old guy, drove away after Sonic took his seat.
"Man, it sure feels good to get outta that place!" thought Sonic. "Now, when's this dream supposed to end?"
"It's time for a field trip, kids!" Somehow, the driver had morphed into Nightmare Sonic. "Don't you worry, I'm a good driver! Just trust me!"
"Uh-oh," thought Sonic. Suddenly, the bus began accelerating to impossible speeds, dodging traffic.
"HOLY CHILI DOGS!" cried Sonic. The bus kept going faster, faster, even faster than Sonic, who began to black out due to the high speeds. "HAAAAAAAAAAAANNNNNNNNNNG OOOOOOOOOONNNNNNNNNNN..."
Sonic passed out and awoke in a black void. "Well, I guess I got out," he said to himself. "Where am I now? It's like…nothin'. Ah heck, I proved him wrong! I guess I can leave after all!"
"How can you understand, little boy?" said Nightmare Sonic.
