Recently stiles didn't have much sleep. He couldn't read, not a single word. You could see how he kept getting worse, the dark circles under his eyes, getting more pale and being sleepy all day at school. As he said he had nightmares every night. He couldn't sleep well. ... That night you went to his house. You two had to study together because in the class he fell asleep and you wanted to teach him that lesson. After about an hour he placed his head on his open book and fell asleep. You saw it but you decided to not disturb his sleep. But after about 30 minutes he started tremble and mumble under his breath. He was sweating and his mumbling was getting louder. "No...no...stop...stop...help...help... someone help" Tears flowed from his closed eyes.
