A Bill in the Ghost Zone

The Dreamscape?

While Bill was resting, he was consumed by a deep sleep, and felt he had an odd dream. Within his dream, he saw what looked to be the dreamscape. Or in other words, the dream of another being. The only way Bill knew how to get there, was with his previous powers, so Bill was extremely confused, because he was so sure that all of the good ones were gone for the rest of his afterlife.

Bill looked around a bit more to try and figure out whose dream he was in. As he looked around, he saw he was in a place in the dream that looked like a small city. He continued searching for the person whose dream he was accidentally inside of. While he was looking around, he saw a high school, that seemed to be called "Casper High" and sneaked in, to see if the person whose mind he was accidentally invading was in there.

He went into some of the classrooms, as well as the cafeteria. When he floated slowly into the cafeteria, he saw a bunch of teens in the cafeteria, and looked at all the tables, trying to figure out whose dream he was in, because there were dozens of kids.

After a few minutes of trying to figure out, he thought that it would be good to take a break for a while.

When Bill was taking a break, he heard an explosion coming from the cafeteria. Bill flew over quickly, and saw, Danny Phantom? What was he doing here? Unless, Bill thought, What if I went into his mind by accident.

While Bill was lost in his train of thoughts, Danny was defeating his foe, Skulker, and very quickly at that.

Bill looked around, and noticed Skulker was gone, and Danny was holding a... thermos? Maybe the thermos had magic, and that's why Skulker was gone! Danny used the thermos to make Skulker leave! That makes more sense, considering this was a dream.

Just as it seemed like Danny was starting to become more relaxed, a wisp of cold air came out of his mouth, and he wore a look of distress. Danny flew around, looking for something, but Bill didn't know what.

Bill was getting quite exhausted from using his powers so much, even in a dream. He started looking for a place to hide, so he can take a break from using his powers. He found a janitors closet and went in intangibly. As soon as he went in, he stopped using his powers, and felt less exhausted very quickly.

A few minutes after he started his break, he saw someone coming through the wall. It started with a white glove, to a black sleeve. When he saw the black and white, he knew exactly who was coming through.

Right when they came in, there was a flash of bright light that filled the closet. Then there was a teen with raven hair, and bright blue eyes.

"Bill?!"

"Umm. Heyyy Danny,"

"What are you doing here?"

"It was an accident?" Bill replied, seemingly confused.

"What do you mean?"

Before Bill could answer, there was a loud bell ringing.

"Oh crap! I need to go," Danny said.

Bill awoke with a start, very confused. He flew quickly out the door to his lair, and as fast as he could went straight to the Fenton Ghost Portal, to tell Danny about what happened.
