Me and QuantumParadigmShift had a really hard time thinking of what should happen next. But here's what we made.

Mira looked at Astral with worry. Astral slowly woke up. Hearing Yuma calling his name. Astral groaned in pain as he came to. "W-what happened?" Astral asked confused. He couldn't remember anything that had just happened only minutes ago. His headache coming back. "You seemed to be sleepwalking, and you were talking to something." Mira explained. "I don't remember falling asleep or talking to anyone." Astral said, holding his head.

Yuma looked a his brother worried, knowing exactly what happened. "Yuma, what's with the look?" Mira asked him. "It's nothing mom." Yuma replied, not wanting to worry his parents. She let him off the hook, more concerned about what happen to Astral. Kari came down the stairs and asked "What's going on down here? I heard yelling."

"Astral was sleepwalking. Sorry to worry you." Mira said, looking up at Kari. "Didn't he sleepwalk while on the camping trip?" "I believe that's what happened." Mira replied. Yuma wanted to say what really happened, but held back for fear of scaring his parents and Astral.

Astral sat there trying to figure out what happened, but for the life of him he couldn't remember. "It's getting late, you kids should go to bed." Mira said. Yuma and Astral nodded, heading off to the there shared room in awkward silence.

"Yuma, could you tell me what happened please?" Astral asked, breaking the silence. "Where do I start?" Yuma said, trying to figure out the best way to explain the situation to his brother. "I remember coming home, that's when my headache came back. I also heard a strange voice in my head telling me to come to it." Astral said, as they walked back to there room. "Was it him again?" Yuma asked.

"I don't know who you're talking about?" Astral said, looking at his brother confused. "Never mind." If Astral didn't know Yuma figured it would be better not to worry him about it. Astral looked at Yuma worried. 'What is he keeping from me?' He thought as they walked into there room.

Yuma fell straight onto his bed only just realising how tired he really was. Astral looked out the window, then tuned around when he heard Yuma snoring. Astral smiled 'Yuma.' he thought as he got into bed. The room was perfectly still and silent, apart from Yuma's snoring. Yuma's snoring carried Astral to sleep. But unknown to the sleeping brothers, an evil Number was watching them.

Thank you so much QuantumParadigmShift for your idea of taking turns writing a sentence.
